Well, last Tuesday we had New York with 291 delegates on the Democratic side, and today five Northeastern states are up at once with a combined 462 more. This looks like one of those rare times that the preferences of the East Coast will have a major effect on choices the nation makes-28% of all the delegates left in the rest of the race will be chosen by this time tomorrow. Here’s where things stand:

Democrats

First off, hoo-boy was I wrong! I said last week that I thought there were signs that Bernie Sanders was going to do better in New York than the polling seemed to indicate. In fact, he got shellacked in New York 58%-42%, a proportion pretty much matching what the polling averages were indicating.

Looking back, I would say that, whatever traces I thought I was sniffing, I should have been a good data-head and really crunched the numbers, because I was badly under-estimating the effect of New York being a closed primary. It’s been observed that Sanders has drawn a lot of his support from voters who register Independent, who can participate in states that have open primaries, but can’t in states with closed primaries. Indeed, if you crunch the numbers on averages of non-Southern open primaries vs. closed primaries, you find the following:

Sanders wins a narrow majority of total votes in open primaries, but has lost the closed primaries 47-53. All five of today’s states have closed or semi-closed primaries, which means Sanders will not be picking up cross-over voters. Thus, you can probably take the polls that show him facing double-digit losses in Maryland & Pennsylvania at face value. His best bets for the night look like Connecticut and Rhode Island, where he’s narrowly behind:

If he ends up 0-5 on a night when 28% of the remaining delegates are up, that’s not going to silence the voices calling for him to admit the game is up. Narrowly winning 2 of the smaller states, both from his native New England, won’t either. He’ll certainly have the money and the enthusiastic base of supporters to stay in until the end. There’s even an open primary coming up next week, Indiana, and he remains within striking distance in polling of the largest state of all, California. And a decent argument can be made that he should stay in for the good of his movement, and democracy in general. But in terms of realistic chances, the New York blowout made his already up-hill shot even steeper, and tonight is liable to make it steeper still.

Republicans

In a certain sense, the Republican side is much clearer, and in a certain sense, it’s murky as %$#@. After a very strong New York last week, Trump is showing solid leads in all five states tonight, and the Republican delegate rules are liable to expand his haul even further.

But behind the scenes, Cruz continues to have a much better ground game for the nuts and bolts of picking up delegates that are still being chosen in state conventions even after the voting has ended. In the current Republican game of delegate-by-delegate attrition, in which a Trump who hasn’t reached the required 1,237 delegates by the convention could have serious problems thereafter, every bit counts.

And then there’s the alliance! Cruz and Kasich are strategically agreeing to stay out of each other’s way in several of the remaining contests. This may indeed be too little, too late, but it does stand a decent shot of handing Cruz Indiana next week, and getting Kasich several Western States. If it does work, Cruz getting all 57 of the winner-take-all delegates next week could seriously complicate Trump’s remaining math. If it doesn’t, that 57 plus his haul from tonight will probably put Trump on track to get close enough to the 1,237 that the game is, effectively, over.

Stay tuned!
