Iowa held an election for the president of the United States on November 8, 2016. The state held caucuses for the Republican and Democratic Parties on February 1, 2016. Iowa was considered a key battleground state in the 2016 general election.

HIGHLIGHTS
  • Donald Trump won Iowa in the general election.
  • Iowa had six electoral votes, which was 1.1 percent of the 538 electoral votes up for grabs in 2016 and 2.2 percent of the 270 electoral votes needed to win the general election.
  • Between 1900 and 2016, Iowa cast votes for the winning presidential candidate 76.67 percent of the time. In that same time frame, Iowa supported Republican candidates more often than Democratic candidates, 66.67 to 33.33 percent. The state leaned Democratic, however, in presidential elections between 2000 and 2016. In 2016, Iowa was a key battleground state.
  • Iowa's caucuses on February 1, 2016, marked the official beginning of the presidential nominating process for both parties. Hillary Clinton narrowly won the Iowa Democratic caucuses with 49.84 percent of the vote. Ted Cruz won the Iowa Republican caucuses with 27.7 percent of the vote.

    Electoral votes

    See also: Electoral College

    The president of the United States is not elected by popular vote but rather by electors in the Electoral College. In fact, when Americans vote for president, they are actually voting for a slate of electors selected by members of Democratic and Republican state parties or nominated in some other fashion. Under this system, which is laid out in Article 2, Section 1, of the Constitution, each state is allocated one electoral vote for every member of their congressional delegation, meaning one for each member of the U.S. House and one for each of their two Senators.

    Iowa electors

    In 2016, Iowa had six electoral votes. Iowa's share of electoral votes represented 1.1 percent of the 538 electoral votes up for grabs in the general election and 2.2 percent of the 270 votes needed to be elected president. 2016 electors in Iowa were chosen by the central committees of state political parties.

    "Faithless electors"

    The U.S. Constitution does not dictate how presidential electors are to cast their votes, but, in general, electors are expected to vote for the winner of the popular vote in their state or the candidates of the party that nominated them to serve as electors. Electors who choose not to vote for the winner of the popular vote or the candidates of the party that nominated them are known as "faithless electors." Faithless electors are rare. Between 1900 and 2012, there were only eight known instances of faithless electors.

    Several states have passed laws against faithless electors and require electors to vote for the winner of the popular vote in their state, for the candidate of the party that nominated them to serve as electors, or in accordance with any pledge they may have been required to make at the time of their nomination. In states with these types of laws, faithless electors can be fined or replaced, or their votes can be nullified.[5][6]

    Iowa was one of 20 states in 2016 without a law seeking to bind the votes of presidential electors.

    Polling

    Iowa polls (2016)

    Ballotpedia's battleground state polling averages were based on polls that came out over a 20- to 30-day period. For example, an average might have covered all polls that were released for a state between September 1, 2016, and September 30, 2016. They were not weighted. Polling averages were checked and updated daily.

    Ballotpedia Battleground Poll

    See also: Ballotpedia's battleground poll, 2016

    Ballotpedia partnered with Evolving Strategies and surveyed voters across seven battleground states (June 10 – 22) regarding their vote preference. We tested six election scenarios. In one set, we matched Hillary Clinton (D) in a series of two-way contests with Donald Trump (R), Ohio Governor John Kasich (R), and House Speaker Paul Ryan (R). In the second set, we matched these same candidates in a series of three-way contests that also included former Governor Gary Johnson. In all seven states, Clinton polled higher than Trump. Comparatively, John Kasich polled ahead of Clinton in five of the seven states, and Paul Ryan polled ahead of Clinton in three states. See the table below for the battleground poll results from Iowa.

    In Iowa, the Libertarian Party nominee, Gary Johnson, saw his highest polling against Donald Trump and Hillary Clinton. Johnson polled at 16 percent compared to Clinton’s 38 percent and Trump’s 36 percent.

    State campaign staff

    Prior to the November 8, 2016, election, each campaign put in place paid staff, volunteers, and political operatives in each state in efforts to gain votes and influence voter turnout on election day. The following details some of the key staff for each campaign in Iowa.

    Hillary Clinton

    For Hillary Clinton's campaign, state operations nationwide were overseen by Marlon Marshall, the campaign's director of state campaigns and political engagement. The key staff in Iowa consisted of:

    Hillary for America 2016 Logo.png

    Kane Miller, State director: Miller began working on Clinton's campaign as the Polk County, Iowa, field director for the caucuses. He went on to direct the campaign's efforts in the Nebraska and Utah caucuses. Miller previously worked as a field organizer on both of Barack Obama's presidential campaigns.[7]
    Troy Price, Senior state advisor: Price was Clinton's political director during the Iowa caucuses and is the former executive director of the Democratic Party of Iowa. Price previously worked for former Gov. Tom Vilsack (D) and was executive director of One Iowa, the state's biggest LGBT advocacy organization.[8]

    Donald Trump

    For Donald Trump's campaign, state operations nationwide were overseen by Michael Biundo, the campaign's senior political advisor. The key staff in Iowa consisted of:

    Iowa Caucuses

    Democrats

    In the Iowa Democratic caucus, Hillary Clinton claimed victory over Bernie Sanders with 49.8 percent of the vote, 0.2 percentage points higher than Sanders' 49.6 percent. This was the narrowest margin in caucus history up to this point.[10][11]

    After concerns were raised about the execution of the Democratic caucus, the Iowa Democratic Party agreed to review the results. Nearly a week after the contest, on February 7, 2016, the state party announced revised results after finding “reporting errors” in several precincts. The Sanders campaign had pushed for a broader review. Clinton’s share of the delegates awarded was revised slightly downward, to 49.84 percent, while Sanders' total was bumped up to 49.59 percent. Former Democratic presidential candidate Martin O'Malley also had a small gain, finishing with 0.54 percent.[12]

    According to entrance polls, Sanders won 84 percent of 17-to-29-year-old voters, and 58 percent of voters between the ages of 30 and 44, while Clinton won 14 percent and 37 percent of those voters, respectively. She did better with older voters winning 58 percent of those between 45 and 64 and 69 percent of those 65 and above. Sanders won 35 percent and 26 percent of those voters, respectively.[13]

    Clinton won 45 percent of voters who said they made their decision on who to support on caucus day. Sander won 42 percent of that same group. Clinton won 54 percent of voters who said they made their decision before January, while Sanders won 42 percent of those voters.[13] According to the Democratic data, Clinton won 61 counties and Sanders won 37 counties. That compares with 2008 when Barack Obama won 40 counties, John Edwards won 30 counties and Clinton won 25. Clinton won six of the top 10 counties with the highest percentage of residents with a bachelor’s degree, while Bernie Sanders won four. Clinton won eight of the top 10 counties with the lowest percentage of residents with a bachelor’s degree, where Sanders won only two of those counties. Clinton won nine of the state's 12 counties in metro areas with a population between 250,000 and 1 million, and Sanders won three. Sanders won five of the nine counties with metro area populations of fewer than 250,000 residents, while Clinton won four. Clinton won 77 percent of voters whose priority they said was to win the general election, compared with Sanders' 17 percent, according to entrance polling. But Sanders won voters, more than eight-to-one, who wanted a candidate who was “honest and trustworthy.”

    Entrance polling showed that Sanders won 59 percent of first-time caucus attendees, while Clinton won 35 percent. Clinton won 59 percent of voters who have attended a caucus before, with Sanders taking 35 percent of those voters.

    In contrast to Iowa Republicans, Iowa Democrats have a nearly perfect track record of predicting the eventual party nominee in six contested races, only faltering twice: in 1992, when former Iowa Sen. Tom Harkin won the caucuses, and in 1988, when former Rep. Richard Gephardt (D-Mo.) won. And when it comes to choosing the general election winner, Iowans have predicted correctly twice: Jimmy Carter in 1976 and Barack Obama in 2008. [14]

    Democratic voter turnout didn't rise to the level of 2008, when a record 239,872 voters participated.[15] But Democrats did set the second-highest turnout record in 2016, when 171,517 voters showed up to caucus.[16]

    Republicans

    On the Republican side, Ted Cruz beat out Donald Trump 28 percent to 24 percent. Marco Rubio came in a close third, with 23 percent.[17]

    Entrance polling showed that Rubio won 28 percent of voters who said they made their decision on who to support on caucus day, compared with 22 percent for Cruz and 15 percent for Trump. Rubio also won 31 percent of those who said they made their mind up "in the last few days," where as Cruz won 27 percent and Trump won 13 percent. Rubio and Trump both won 22 percent of independents and Cruz won 19 percent of that vote.[13] Cruz's organization was decisive. His win was a victory for retail politics and a more traditional get-out-the-vote operation, compared to Trump's lighter footprint in the state. Cruz spent months touring the state—managing to visit all of the state's 99 counties[18]—discussing his opposition to abortion, gay marriage, compromise by Republican leaders in Congress and other issues that resonated with the state's evangelical voters.[19]

    Similar to the previous two Iowa GOP caucuses, it was the conservative vote that played a significant role in helping to determine the winner. Cruz won 43 percent of the party’s most conservative voters, followed by Trump with 21 percent, according to entrance polling.[20]

    According to a Ballotpedia analysis of the data, Cruz won 58 counties, Trump won 34 counties and Rubio won five. That compares with 2012 when Rick Santorum won 56 counties, Mitt Romney won 16 counties and Ron Paul carried 10. Of those counties, Cruz carried eight of the top 10 counties with highest percentage of residents with a bachelor’s degree, while Trump won the other two. Cruz also won eight of the top 10 counties with the lowest percentage of residents with a bachelor’s degree, where as Trump won one of those counties.

    With regard to population, Cruz won 10 of the state's 12 counties in metro areas with a population between 250,000 and 1 million, while Trump won one. However, Trump won five of the nine counties with metro area populations of fewer than 250,000 residents, while Cruz won four. Cruz and Trump split the vote in 20 rural counties. Cruz won 10 counties with populations less that 2,500, and Trump won nine.

    Cruz's victory came despite several polls showing Trump leading, including The Des Moines Register poll.[21] Beating expectations gave Cruz momentum heading into the next contest, the New Hampshire primary scheduled for February 9, 2016.

    The Republican winner of the caucuses was chosen as the eventual nominee twice in six contested races between 1980 and 2012: Robert Dole in 1996 and George W. Bush in 2000—the only Iowa winner on the Republican side to become president since before Iowa became the first nominating event in 1972.[22][23]

    Iowa Republicans also set a record. Roughly 182,000 Republican Iowa caucus-goers turned out, with nearly all precincts reporting, breaking the record of 122,000 in 2012.[24]

    Rubio also outperformed expectations coming in at third with 23 percent of the vote, closer to the second-place spot than expected. "This is the moment they said would never happen. For months, they told us we had no chance," Rubio said in a speech after the caucuses.[25] Entrance polling showed that Rubio won 44 percent of voters who thought a candidate's most important attribute is the ability to "win on November," while Trump won 24 percent and Cruz won 22 percent. Trump won 66 percent of voters who prized a candidate who "tells it like it is" and 33 percent of voters who want a candidate who "can bring needed change." Cruz won 11 percent and 25 percent of those voters, and Rubio won 4 percent and 17 percent, respectively.

    How the caucuses work

    Cast as gatherings of neighbors and the ultimate in grassroots political participation, the Iowa caucuses allow eligible Iowa voters from each party caucused to meet separately at 1,681 precincts across the state's 99 counties to declare their preference for their party's nominee. To be eligible to caucus, state parties required voters to reside in the precinct in which they wished to participate, to be registered to vote in Iowa and to be at least 18 years old on Election Day.[26][27][28]

    Iowa counties map.png

    At both the Republican and Democratic caucuses, advocates for each candidate played a key role by seeking to change the minds of their fellow attendees or sway the undecided.

    The Republican preference poll process is relatively straightforward. Once the caucus is called to order, the caucus chair invites anyone to speak briefly in support of his or her favored candidate. After all speeches have concluded, each eligible caucus voter is given a piece of paper to either write or mark their choice. After everyone has filled out their secret ballot, the votes are counted in the precinct and announced to the room. All the precincts of a county are collected by party leadership and then reported to the Republican Party of Iowa to tabulate the state results. Other business is also decided at the caucus, including planks in the Republican Party of Iowa’s platform, members of the county’s Republican central committee, and delegates to the county convention.[28][29]

    The Democratic caucus is more complicated. After speeches on behalf of candidates, participants physically move into different parts of the room to show which candidate they support. The size of a candidate’s support is counted, and candidates who don't have enough support are deemed non-viable. The viability threshold was 15 percent of the participants in the room, a hurdle that Martin O'Malley could not clear, and he subsequently suspended his campaign.[30] Members of the non-viable groups can try to attract more people to their candidate, disperse and join other candidate groups, or remain uncommitted. This is known as the realignment process. [31] The number of votes each candidate gets determines what percentage of that precinct's delegates will represent that person at the county convention. Realignment makes it important for Democratic campaigns to not only line up supporters of their candidate but also try to identify the second choice of each caucus attendee in case their first choice is not deemed viable. Democrats also take care of other business, including electing delegates to the county convention and local party leadership.[28][29]

    The Iowa caucuses are also traditionally the first serious test of a campaign's organizational efforts and its ability to turn out voters.[32] The more supporters a campaign can get out to caucus, the better chance of success it will have. And in 2016, caucus organization was the difference, with top candidates relatively close in the polls the week before Iowans began the nomination process.[33][34]

    Democratic Party

    Iowa had 51 delegates at the 2016 Democratic National Convention. Of this total, 44 were pledged delegates. National party rules stipulated how Democratic delegates in all states were allocated. Pledged delegates were allocated to a candidate in proportion to the votes he or she received in a state's primary or caucus. A candidate was eligible to receive a share of the state's pledged delegates if he or she won at least 15 percent of the votes cast in the primary or caucus. There were three types of pledged Democratic delegates: congressional district delegates, at-large delegates, and party leaders and elected officials (PLEOs). Congressional district delegates were allocated proportionally based on the primary or caucus results in a given district. At-large and PLEO delegates were allocated proportionally based on statewide caucus results.[35][36]

    Seven party leaders and elected officials served as unpledged delegates. These delegates were not required to adhere to the results of a state's primary or caucus.[35][37]

    Republican Party

    Iowa had 30 delegates at the 2016 Republican National Convention. Of this total, 12 were district-level delegates (three for each of the state's four congressional districts). District-level delegates were allocated on a proportional basis; each candidate who won a percentage of the statewide vote in Iowa's caucuses received a share of the state's district-level delegates.[38][39]

    Of the remaining 18 delegates, 15 served at large. At-large delegates were allocated proportionally based on the statewide vote; any candidate who won a percentage of the statewide vote was entitled to receive a share of Iowa's at-large delegates. In addition, three national party leaders (identified on the chart below as RNC delegates) served as bound delegates to the Republican National Convention.[38][39]

    Straw poll

    See also: Presidential election, 2016/Straw polls

    Iowa Republicans first began conducting a straw-poll—an informal and unofficial opinion poll—for president in 1972. The Iowa Republican Party, however, voted to end the Iowa Straw Poll on June 12, 2015. The poll was the recipient of scrutiny due to its inability to actually predict the Republican nominee.[40] Major contenders for the Republican nomination had slowly been announcing they would not participate in the poll over the weeks leading up to news of the cancellation. Former Rep. Michele Bachmann (R-Minn.) won the straw poll in 2012.
