The Sanders campaign has come much further than almost anyone expected, to the point where Sanders can have a lot of influence on the shape of the race. But with influence comes responsibility, and it’s time to lay out some guidelines for good and bad behavior.

The first thing to say is that it’s still very unlikely that Sanders can win the nomination. Don’t tell me about national polls (and cherry-pick the polls that show your guy getting close); at this point it’s all about delegate counts, where Clinton has a substantial lead with the voting more than half over. The Times’s Upshot has a nice calculator that takes account of what we know about demographic factors – Sanders does well in very white states and in caucuses, not so much elsewhere – and lets you experiment with various overall leads in what remains of the race. To overtake Clinton in pledged delegates, Sanders would need to win by about a 13 point margin from here on in:

Nothing in what we’ve seen so far suggests that he’ll come anywhere close to that. He’ll probably win Wisconsin next week, but that’s a demographically favorable state for him, so unless it’s a huge blowout (which the polls aren’t showing), Clinton will still be very much on track for the nomination.

Now, as the bumper stickers don’t quite say, stuff happens. But at this point it’s something like a 90 percent probability that Hillary Clinton will be the Democratic nominee. Anyone denying that arithmetic is basically pulling a con job on Sanders supporters.

So what does that say about appropriate behavior on the part of her rival? Two things, I’d argue.

First, the Sanders campaign needs to stop feeding the right-wing disinformation machine. Engaging in innuendo suggesting, without evidence, that Clinton is corrupt is, at this point, basically campaigning on behalf of the RNC. If Sanders really believes, as he says, that it’s all-important to keep the White House out of Republican hands, he should stop all that – and tell his staff to stop it too.

Second, it’s time for Sanders to engage in some citizenship. The presidency isn’t the only office on the line; down-ballot races for the Senate and even the House are going to be crucial. Clinton has been raising money for other races; Sanders hasn’t, and is still being evasive on whether he will ever do so. Not acceptable.

Oh, and the Sanders campaign is saying that it will try to flip superdelegates even if it loses the unpledged delegates and the popular vote. Remember when evil Hillary was going to use superdelegates to steal the nomination? Double standards aside, what makes the campaign think that he will get any backing from a party he refuses to lift a finger to help?

It’s important to realize that there are some real conflicts of interest here. For Sanders campaign staff, and also for anyone who has been backing his insurgency, it’s been one heck of a ride, and they would understandably like it to go on as long as possible. But we’ve now reached the point where what’s fun for the campaign isn’t at all the same as what’s good for America.

Sanders doesn’t need to drop out, but he needs to start acting responsibly.
