After today, I don’t think a Trump win is a foregone conclusion at all. It’s very striking that Trump’s support in open primaries is much higher than it was in Oklahoma, a closed primary. Trump only got 28% of the vote in Oklahoma compared to the big open primary states where he generally got more like 40%, and even 50% in Mass.
Furthermore, in open primary states Republican turnout was setting records, while Democratic turnout was down significantly. This leaves open the possibility that Trump’s support is essentially the 25-30% of Republicans that have typically gone for outsiders like Pat Buchanan and Ross Perot. If so, that means that Trump is picking up maybe 10-20% support from disaffected Democrats and independents who are crossing over and voting for him in the open primaries. And I wouldn’t be surprised if there was some strategic voting by Democrats, trying to spoil the Republican campaign by helping Trump.
The sample size is small, so this could just be a fluke. But there’s a natural experiment coming up: This Saturday there are four caucuses running, and they are all closed. If Trump comes out of Saturday with an average of 25% to 35% of the vote he could be in trouble, because a lot of the states yet to hold primaries and caucuses are closed, and some of those are big and winner-take-all.
Rubio looks like he’s far behind, but that could be an illusion based on geography - Cruz has been through his best states now, but Rubio’s are ahead of him. If he takes Florida on March 15 and he and Cruz win in this weekend’s caucuses, it’s going to be a 3 person race with a 3-way split in delegates. And Trump will not have the momentum any more.
Anyway, I don’t know how likely it is, but it does point out that there are still scenarios here where any three of the current leaders could win, and also scenarios where the party cuts a deal with Cruz and Rubio and even Kasich to stay in the race right through all the primaries just to try to deny a majority of delegates to Trump. That would cause a contested convention, at which point the party establishment can basically give Trump the boot.
This Saturday could be big. Cruz is only behind Trump by 93 delegates. If we give Rubio Florida on March 15, he’s essentially tied with Cruz as he’ll pick up 99 delegates (it’s winner-take-all), and there are 155 Republican delegates up for grabs this weekend, all in closed contests.
And so far, Trump is not tracking towards a majority of delegates. He’s currently losing to the field by 319 delegates to 361 for the other three. If Trump falls off the pace or just stays on it, he’ll go to the convention with a plurality but not a majority of delegates. Now, normally in that case a candidate could wheel and deal and offer cabinet positions and such to other candidates and build a majority. That’s why what Romney did today was so important. By shaming Trump, he’s shaming politicians who help him. Trump might go into the convention to find that all the other candidates left have created a bloc that freezes him out.
Anyway, a guy can dream. But I think this is a realistic, if not likely scenario.
