Here’s How Many Bernie Sanders Supporters Ultimately Voted For Trump
— Fully 12 percent of people who voted for Sen. Bernie Sanders, I-Vt., in the 2016 Democratic presidential primaries voted for President Trump in the general election. That is according to the data from the Cooperative Congressional Election Study — a massive election survey of around 50,000 people. (For perspective, a run-of-the-mill survey measuring Trump’s job approval right now has a sample of 800 to 1,500.)
Political science professor Brian Schaffner of University of Massachusetts, Amherst tweeted the data on Wednesday.
Schaffner’s numbers show that after a bitter Democratic primary, more than 1 in 10 of those who voted in the primaries for the very progressive Sanders ended up voting for the Republican in the general election, rather than for the Democratic candidate, Hillary Clinton.
What drove those voters to Trump? Schaffner dug into that, as well. What it wasn’t was trade, an issue where Sanders was closer to Trump’s philosophy than Clinton’s. At least, the issue of trade didn’t seem to have that much of an impact.
Party seems to have had something to do with it — Sanders-Trump voters were much less likely than Sanders-Clinton or Sanders-third party voters to have been Democrats. Likewise, approval of President Barack Obama appears to be related — Sanders-Trump voters approved of Obama much less than other Sanders primary voters.
