Obama–Trump voters

In the United States, Obama–Trump voters, sometimes referred to as Trump Democrats or Obama Republicans, are people who voted for Democratic Party nominee Barack Obama in the 2008 or 2012 presidential elections (or both), but later voted for Republican Party nominee Donald Trump in 2016, 2020, or 2024 (or all). They might also have voted for Trump's opponents: Hillary Clinton in 2016, Joe Biden in 2020, or Kamala Harris in 2024 (or all except one). Data shows that in 2016, these voters comprised roughly 13% of Trump voters. In 2012, this segment of voters made up 9% of total Obama voters. Seven percent of 2012 Obama voters did not vote at all in 2016, and 3% voted for a third-party candidate. While some analysts consider Obama–Trump voters to have been decisive in Trump's 2016 victory, others have disputed this conclusion.

According to research done by the Democracy Fund Voter Study Group, compared to other voters, Obama–Trump voters have progressive economic views and conservative social views. However, 75 percent of them supported repealing and replacing the Affordable Care Act (Obamacare) according to another survey. Though these voters supported Trump in the 2016 and 2020 elections, they are less supportive of Republicans as a whole, and show a desire to change the status quo.

Florida, Iowa, and Ohio used to be swing states but now they are stronghold red states. These states voted for Obama in 2008 and 2012, but later voted for Trump in 2016, 2020, and 2024. In contrast, Michigan, Pennsylvania, and Wisconsin used to be blue-leaning states (formerly part of the "blue wall") but now they are swing states. These states voted for Obama in 2008 and 2012, but later voted for Trump in 2016 and 2024.
