In my last post on the Republicans I used current polls to try to guess the March 15th results. This was my guess:

Trump +226, Kasich +86, Cruz +36, Rubio +19

Results are not yet final in Missouri, and because it is winner take all in each congressional district as well as statewide, and it is close in most congressional districts, things could still swing there quite a bit. But for the moment, with the best estimates I had from Green Papers, the actual results from the 15th were:

Trump +229, Kasich +81, Cruz +51, Rubio +6

Cruz got a bit more than my predictions, Rubio a bit less. But basically using the polls a couple days out got things pretty spot on. So minus any big changes from Missouri or minor adjustments elsewhere, this was the expected scenario.

So time to look at some graphs, including some I don’t usually bother with…

In raw delegate counts we now have:

Trump 693, Cruz 423, Rubio 172, Kasich 144, Carson 8, Bush 4, Fiorina 1, Huckabee 1, Paul 1

Trump, Cruz and Kasich both look like they made significant improvements, but…

This is the percentage of delegates allocated so far to each candidate. Trump is just BARELY under the 50% mark. Only Trump and Kasich improved on this metric with the March 15th results.

But… looking at the much more useful “% of remaining delegates needed to win” graph…

Everybody except Trump got further away from the nomination after March 15th. In fact, all of them got a LOT farther from the nomination. In fact, almost all the candidates have now been mathematically eliminated from a first round convention win. We knew for a long time that Paul, Huckabee, Fiorina, Bush and Carson were headed there. But it is now official. But Rubio was also eliminated. And despite his “big win” in Ohio, so was Kasich. All of these candidates could get every delegate still outstanding… and still not end up with enough delegates to win.

Only Trump and Cruz still have the possibility of collecting a majority of the delegates before the convention. And Cruz just went from needing 62.14% of the remaining delegates, to needing 79.41%. This is a completely unrealistic number, even if it was a two person race between him and Trump. (For the moment, despite it being impossible for him to get enough delegates, Kasich is staying in, so we still have a three way split, which favors Trump.)

Trump needs 53.07% of the remaining delegates to win outright. Less than that will get us to a contested convention and all kind of chaos. But how likely is Trump to get those sorts of margins? So far of course he has only gotten 47.89% of the delegates. So he does have to improve on his previous performance by about 11%.

This sounds like a lot, but it is probably quite reachable. First, Trump will undoubtedly pick up some of Rubio’s supporters, they won’t all go to Cruz and Kasich. Second, there are a number of winner take all states coming up. Third, a lot of the states that are not winner take all are still winner take most.

Basically, the structure of the primary calendar is DESIGNED to help the front running candidate wrap things up. It is not unreasonable to think Trump will be able to do that. To stop it, Cruz and Kasich between them need to be getting more than a majority of the delegates despite the fact that neither of them has a realistic shot at an outright win. The only plan for those two is to force the contested convention, then win there.

Some places have tried to game out all of the remaining primaries and caucuses, and they conclude that we may in fact not know if we have an outright Trump win or a contested convention until the very last contests on on June 7th. That would be California, Montana, New Jersey, New Mexico and South Dakota. And there is a possibility we won’t even know until after that, because although their numbers are small, some states and territories have actually elected uncommitted delegates, who like superdelegates on the Democratic side are free agents able to vote however they see fit. There is a posisbility (a small one, but non-zero) that these uncommitted delegates may be in a position to determine if there will indeed be a contested convention.

I won’t try to game out the rest of the season, but I will look at next Tuesday… Arizona, Utah, and American Samoa. As usual, looking at RCP for polls, and Green Papers for delegate rules. But guess what? As of today, there has been NO recent polling on any of these three. So we’ll use national polling, but eliminating candidates who have dropped out. So Trump 36.0%, Cruz 21.8%, Kasich 12.0%. Normalized to 100%, that is Trump 51.6%, Cruz 31.2%, Kasich 17.2%..

• Arizona is winner take all. Unless Cruz or Kasich are doing much better there than nationally, Trump gets all 58 delegates.
• Utah is winner take most. If anybody gets over 50%, they get all the delegates. If the estimates above based on national polling are right, Trump gets all 40 delegates. If he doesn’t hit 50%, but still gets a plurality, he is likely to still get almost all the delegates. We’ll estimate 40 to Trump.
• American Samoa might end up electing someone with a commitment, but the expectation given their rules is that all delegates will be uncommitted, so they will just stay TBD in my counts.

Now, either Arizona or Utah COULD go in a completely different direction. As I said, there has been no recent polling. So who really knows? But if Trump ends up winning both, he will likely get something close to 98 delegates out of the two states.

If that happened, that would put the total delegate count at:

Trump 791, Cruz 423, Rubio 172, Kasich 144, Carson 8, Bush 4, Fiorina 1, Huckabee 1, Paul 1

That would give Trump 51.20% of the delegates. He would once again have a majority of the delegates. Trump would then need 446 delegates to win outright. There would be 927 delegates left undetermined at that point. So Trump would only need 48.11% of the remaining delegates to win. Which given his history at that point seems quite reachable.

But continuing to block him might still be within reach. Cruz + Kasich would only need to manage about 52% of the delegates. Which might be possible if they could build on anti-Trump sentiment even in the face of Trump winning. If they can do that is a big open question though. The “I can’t win, and you might not even like me, but vote for me to block the other guy and cause a contested convention where the outcome is completely unknown” case may not be the easiest one to make.

But if Cruz and Kasich can make that case, then it is not over yet.

So then we start looking at North Dakota, Wisconsin, Colorado… and beyond.

Of course, if Trump loses Arizona or Utah, that all changes.

So we will have to wait and see… but if I had to put odds on it, I’m still thinking about an 80% chance that Trump just wins this outright. The structure of the contests themselves are designed to help the front runner, and that is Trump.

[Update 2016-03-18 06:21 UTC – As per Alaska’s rules, after Rubio dropped out they reassigned his delegates to the remaining candidates. Result: Trump +3, Cruz +2, Rubio -5.]

[Update 2016-03-23 01:43 UTC – The Virgin Islands updated their delegate results because the original slate of delegates (all uncommitted) did not end up qualifying under the rules (see here). The original delegates were replaced by alternates. The result for the counts was Rubio +2, Cruz +1, Trump +1.]
