Look, I want Bernie out as much as the next guy, but he really can't drop out after a "win." (I'll call it a win because he got more votes. However, this isn't a win for his campaign. He gained 3 delegates but took 83 off the table. It's not the equivalent of getting a touchdown when you're bind by 5 of them. It's getting a safety when you're behind by 5 touchdowns and fumbling the kick off.) He needs to land the plane, and he needs to do it quickly.
Hillary's going to be about 200 delegates short of the nomination tonight. She only needs Bernie out for narrative purposes, because she's not going to spend another minute worrying about him as evidenced by her Indiana strategy. (Which cost her almost nothing but forced Bernie to blow through $1.6 million for a gain of 3 delegates.)
So, she needs 200 more. There are 175 super delegates left. If she can get 110 or so of them to declare publicly, lose the rest of the May contests by no more than 25 points, she's basically at 2383 and is the presumptive nominee. Bernie then has an excuse to land the plane and be gracious (although I don't think he has tha tin him ,but maybe I'm wrong.)
That should be her campaign strategy going forward. Let Bernie buzz annoyingly in her ear if he wants. It's meaningless. If he actually cares about the issues he's campaigned on (and I believe he does) then he should, of his own free will, turn down the lying and the negativity. I'm not opposed to the DSCC and Schumer reminding him how we all him to caucus with us....provided it's done quietly.
