Pivot Counties
Pivot Counties are the 206 counties nationwide that Ballotpedia identified as having voted for Barack Obama (D) in 2008 and 2012 and Donald Trump (R) in the 2016 presidential election. These counties are sometimes referred to as swing counties by media and political observers.
Ballotpedia defines Pivot Counties won by Trump in 2020 as Retained Pivot Counties and those won by Joe Biden (D) as Boomerang Pivot Counties.
Trump won 181 Retained Pivot Counties across 32 states to Biden's 25 Boomerang Pivot Counties across 16 states.[1][2]
