90 percent of unwavering Sanders supporters plan to vote for Clinton in November
Among the weird scenes from the first day of the Democratic convention in Philadelphia is this one. A truck sponsored by the conspiracy-theory site Infowars toting a billboard reading "Hillary for Prison 2016" rolled up to some pro-Bernie Sanders protesters. Infowars doesn't fit neatly onto the political spectrum, but it's by no means liberal. The Sanders supporters, though, liked what they saw.
This was shortly after the Florida delegation to the convention enthusiastically booed Debbie Wasserman Schultz, the outgoing head of the Democratic National Committee and a member of the House representing the state.
The picture that develops is of a party split by support for and opposition to Hillary Clinton. But it serves as a good demonstration of the importance of keeping anecdotal evidence in context.
Pew Research has been polling on the 2016 campaign for months, allowing it to track attitudes among voters over time. Nearly half of the Democratic electorate, 44 percent, changed their preference over the course of the three surveys Pew conducted. About 3 in 10 supported Clinton, wire-to-wire; about 20 percent Sanders.
Pew asked those consistent Sanders supporters whom they support in the general election. Ninety percent said they back Hillary Clinton.
