I know a lot of people who are scared to death of a Trump presidency and who think Sanders should bow out of the race before the convention. Many wanted him to bow out before the California primaries. I suspect a few of these people just didn’t want the competition for Clinton or think that Sanders is damaging Clinton’s campaign to the point that Trump will win.
To that last point as long as Bernie isn’t lying about Hillary he’s not the one damaging her campaign. She is.
But there is a very good reason for Sanders to stay in the race until the convention. As T.A. Frank points out in this Vanity Fair article:
Every increase in delegates gives Bernie a stronger claim to being heard and appeased when it comes to what happens at the Democratic National Convention in Philadelphia. He has already been granted the privilege of selecting five of the 15 members on the national convention drafting committee (not that it’s mollifying anyone at the moment).
So damaging Clinton or not Sanders needs to stay in until the convention or his “revolution” is still-born. And whether or not Sanders supporters turn their support to Clinton should Sanders lose the nomination isn’t something that is Sanders’ responsibility, it’s Clinton’s. No one is going to support someone they feel is unsupportable and many Sanders supports see Clinton as unsupportable.
This has created a curious state of play in which more centrist Hillary supporters seem to fear Trump a good deal more than the more leftist Bernie supporters do. Some of them probably feel like Susan Sarandon—that the status quo is so unacceptable that a Trump blowup has its merits. Others just resent having Trump held over the head like a stick, threatening to beat them into pro-Clinton solidarity.
Don’t assume that just because you see Clinton as a far less evil than Trump that Sanders supporters feel the same way. Heck, I don’t feel that way and if those two are the only choice I have no reason to vote because between the two, I don’t care!
