To me, the Democratic primaries are over. Hillary has won. Time to focus on the GE.

15. He already gets the plummy

speaker's spot in June just for having competed. There's no requirement of even carrying a single delegate, although of course he did far better than that.

In terms of leverage, he's dragged Clinton to the left on some things, but she's dragged him to the left on others (gun control and immigration, most notably). So I'm not sure how effective staying in will be at this point, or his motivations for doing so.

It clearly isn't to win, the campaign stopped working an all-state strategy before Super Tuesday and started to focus on smaller states. It's not to build a coalition, they're making no effort to do that (and the clock is ticking).

So I have no clue. I have a guess...but it's rather unpleasant and would earn me a hide if I suggested it for daring to criticize.
