David Costello

Party: Democratic Party

Incumbent: No

Political Office: None

Submitted Biography: "I was born in Bangor in 1960 and raised in Old Town, Maine by his mother Gail, and maternal grandparents, Alfred and Pauline Baillargeon. My father John, an Army veteran and AFL- CIO organizer, died in 1968 at the age of thirty-one. The grandson of French and Irish American shoe, textile, and railroad workers, I learned the value of hard work at an early age. And, like many in Maine, I was the first in his family to earn a bachelor’s degree and a master’s degree having worked my way through the University of Maine, George Washington University, and the London School of Economics and Political Science. With more than twenty-five years of senior- level government experience, I believe that I have the knowledge and skills necessary to make a meaningful difference in Washington. During my career, I have managed complex, multi-million-dollar programs both in the U.S. and overseas - including initiatives to combat climate change, revitalize communities, protect public health and the environment, and advance peaceful democratic change in such conflict-torn countries as Cambodia, Haiti, Bosnia, Croatia, Serbia, and Kosovo. "

Key Messages

To read this candidate's full survey responses, click here.

Partisan gridlock abounds and our imperfect democracy is in danger of becoming even more flawed. To fix it, we need to do more than simply change who we elect every two to six years. We need to substantially reform our governing practices and institutions, and we need to eliminate the excessive and corrupting influence that money, wealth, and disinformation have over our politics and government.

I am running for the United States Senate because I want to advance long-overdue reforms that will not only help end gridlock in Washington but also help in protecting our rights and freedoms and assist in addressing such pressing problems as climate change, uneven economic prosperity, inadequate health care, shoddy infrastructure, under performing schools, increasing gun violence, and insufficient retirement security. I am also running because I want to help in ensuring that all Mainers are provided with the education, job skills, and other life-enriching opportunities to thrive. Having grown up in a working-class family I can appreciate the challenges confronting many of Maine’s less affluent families.

As Senator, I will back efforts to: enact pro-democracy campaign finance reforms; impose term limits and retirement age requirements on federal judges, including Supreme Court justices; create an independent Government Accountability and Performance Commission; abolish the Electoral College; end gerrymandering and the Senate filibuster; overhaul of the U.S. House and Senate to ensure greater accountability and more equal representation; impose 24-year term limits on members of the U.S. House and Senate; and streamline our Constitution’s amendment process so that it is no longer virtually impossible to update our national charter.
