Speaking to CNN's Chris Cuomo this morning, Bernie Sanders said his vote will in "all likelihood" go to Clinton in November. Sanders stopped short of a full-on endorsement of the presumptive Democratic nominee for president, and, despite his equivocal phrasing, he said he wouldn't vote for Trump or Gary Johnson. Cuomo didn't ask if he'd vote for Jill Stein, but it seems unlikely since Bernie won't even return her e-mails.
When Cuomo asked whether Bernie's supporters will vote for Trump over Hillary, as some Sanders supporters say they might, Bernie said, “The people who supported me are not going to vote for a bigot, somebody who has as the cornerstone of his campaign insulting Mexicans and Latinos and Muslims and women and veterans and African Americans.”
Sanders supporters in blue states such as our very own Washington who are considering writing in Bernie or voting for a third party candidate can do so without, perhaps, implicitly supporting Trump. But, according to Noam Chomsky, progressives in swing states don't have that luxury: "If Clinton is nominated and it comes to a choice between Clinton and Trump, in a swing state, a state where it’s going to matter which way you vote, I would vote against Trump, and by elementary arithmetic, that means you hold your nose and you vote Democrat. I don’t think there’s any other rational choice."
