Colorado is odd in that it dribbled out delegates over a couple of weeks. The 6 from the 1st and 6th congressional districts were already included when the Michigan results came out. Those 6 were all Cruz. Since then I added notes about the rest of Colorado’s congressional districts to the Michigan post. Cruz won all 15 of those delegates. Then yesterday Cruz won all 13 at large delegates.

There are 3 more delegates from Colorado who are state party leaders and have not yet expressed a preference.

But Cruz has won all 34 of Colorado’s delegates that were available via the caucus process.

Since March 23rd, Trump has gotten bad news in Alaska, American Samoa, Louisiana, North Dakota, Wisconsin and Colorado. Some of those were “new” results in states, others were just updates as more information came in. Either way, none of those updates went Trump’s way.

Lets look at the chart:

After Arizona and Utah Trump needed 52.22% of the remaining delegates to be on a winning pace.

Since then the delegate deltas have been Cruz +78, Trump +6, Rubio +4, Kasich +1. And that Kasich delegate is being generous interpreting one uncommitted delegate’s comments. That might actually be a Cruz delegate in the end.

So Cruz got 78/89 = 87.6% of the delegates.

Trump got 6/89 = 6.7% of the delegates.

Needless to say this is far below the 52.22% Trump needed to improve his position.

Instead, he goes from needing 52.22% of the remaining delegates to needing 57.07%. This is huge change.

Winning 57.07% of the delegates would represent a 23% improvement over the 46.46% of delegates pace he has so far. That is a pretty substantial improvement.

Trump is in the worst position he has been so far. This is not where he wants to be. Everything is going in the wrong direction.

But is it time to assume a contested convention yet? The drum beat about that has certainly begun.

I could do my usual of calculating an estimate for New York from current polling, and then look where that puts us, but other folks have done more in depth projections. I’ll specifically point out two:

• Nate Cohn at the New York Times: Donald Trump’s Path to 1,237 Is Not Mission Impossible
• Sam Wang at Princeton Election Consortium: Current Polls Favor A Trump Delegate Majority

Both of these two outline scenarios where Trump can still get to 1237. These are not highly unlikely scenarios like those required to get to a Sanders win on the Democratic side, but rather perfectly reasonable possibilities given current polling data. Trusting current polls completely, Wang actually gets a 92% chance of Trump getting the delegate majority. When he adjusts for the fact Cruz has been over performing his polls, that drops to 70%. This is by no means certain, but it is still more likely than not.

In addition you can run your own simulations at The Upshot or FiveThirtyEight. With either of these it is not that hard to get Trump to 1237. Try it yourself. It is fun.

My own take is that some of Wang’s assumptions about how uncommitted delegates will break is a bit generous to Trump given his performance so far with uncommitted and unbound delegates. So 70% chance of an outright majority seems a bit high.

In the last Curmudgeon’s Corner podcast I said my gut feel was that we have a 60% chance of a multiple-ballot convention at this point. Which would mean a 40% chance that Trump wins outright. (I allowed for some additional chance of convention shenanigans like trying to change the rules to unbind delegates on the first ballot, or that the results of there 1st ballot would be unclear until the actual vote due to uncommitted delegates.)

Trump was EXPECTED to do badly in Colorado and Michigan… perhaps not quite this badly, but still it means that it is easy to get distracted by notions of “momentum” that may or may not be real. The fact that Trump did well in Arizona, but then badly in Colorado does not represent a change in the state of the race. It is just a function of the makeup of those states and the calendar. To see if things have really changed from being “right on the edge between a Trump win and a contested convention” we need to see deviations against how the remaining states are expected to play out.

We haven’t seen that quite yet.

But all the anti-Trump forces are pushing against him hard and Trump has no margin for error in the remaining states. He has to do well in all the places he is expected to do well. He might actually need to exceed expectations by a bit. If he starts dipping, even a little bit, then we are at a contested convention. And given what appears to be Cruz’s skill at collecting “ghost delegates” who are bound to Trump on the first ballot but who really support Cruz, a Trump loss on the first ballot almost certainly means Cruz (or maybe someone else, but probably Cruz) wins on a later ballot.

Keep watching New York and if Trump stays over 50% in the popular vote, which will get him all or almost all of the delegates. That is the next big test. If Trump underperforms expectations in New York, we almost certainly will have a multi-ballot convention. If he matches or exceeds expectations, then the path to an outright Trump win remains open.
