Brokered Convention Math: Not Trump Needs Pennsylvania, Illinois, Ohio

Prior to Super Tuesday, we thought there were no scenarios in which Donald Trump didn’t go on to get the 1,237 delegates needed to win on the first ballot at the Republican National Convention. Trump had a slightly weaker than expected delegate haul than we expected, and there are a few glimmers of hope for the #NeverTrump crowd.

It turns out that Mitt Romney is probably right:  the most likely way for Trump to not win is for Marco Rubio and John Kasich voters to vote strategically.  Our latest projections, which include Trump taking the big winner-take-all states of Florida, Ohio, Pennsylvania, and Illinois shows Trump taking the majority in after April 26.  This is mostly on the strength of a huge March 15 haul for the candidate, where we see him picking up over 500 delegates to reach 881 of the 1,237 needed.

If Trump wins the big winner-take-all states, he should wrap it up before May 1.
If Trump wins the big winner-take-all states, he should wrap it up before May 1.

There is no world in which the non-Trumps get block his first-ballot nomination without a Rubio victory to claim Florida’s 99 delegates. Trump leads leads Kasich in Ohio 30.2% to 26.6%.  There’s no polling for Puerto Rico’s 23 winner-take-all delegates, but we’ll assume for the sake of argument that Trump doesn’t win that one.  Move those to the other side, and Trump’s victory moves all the way to the final day, but he still wins.

So what’s the most-likely non-Trump path? Polling beyond March is spotty, but if Trump loses Florida, Pennsylvania, New Jersey, Ohio, Puerto Rico, and California, you’ve got a contested convention. He currently holds double-digit leads in PA (April 26) and NJ (June 7), and Cruz may be within a few points in California, but there haven’t been any good polls there forever (probably because most normal nomination contests would be wrapped up by the final day.

Trump just misses assuming he loses Florida, Ohio, California, Puerto Rico, and New Jersey...all winner-take-all contests.

A simpler take is this:  If Trump wins Florida and Ohio, there is virtually no option to stop him.  If he loses those, there’s a possibility to block him. If he also loses Illinois on March 15, that would suggest the numbers we’re using to project are too high, and Trump may fall several hundred delegates short.

Of course, all of this assumes that Trump loses a contested convention; it’s hard to imagine what policy concessions the other candidates can offer true Trump delegates. Trump has between 250 million and 10 billion (depending on your source) convincing reasons to persuade other delegates to break camp if he needs to.

Super Tuesday quick take: Great for Cruz, Par for Trump, and Holding for Rubio

The delegate math for the Republicans is difficult, with each state having its own rules down to the Congressional district level.  More than 30 hours after polls closed, the majority of the states are still figuring out how to apportion the delegates.  We have updated our projections in a simple way:  the leading candidate in the state gets the balance of the delegates still on the table.  This rough math generally favors Trump, but also gives Cruz a boost in Texas.

Based on those numbers, Trump fell short of our delegate projection by 71 (we saw him winning 358, but now see that coming out to 277). Cruz overshot: we see him winning 237 against the 165 we projected. While the news cycle for Rubio is certainly negative, he slightly overshot based on stronger-than-projected showings in Minnesota and Virginia.

The biggest deltas in our projection are Oklahoma, Minnesota, and Alaska.  The latter two are simply because there weren’t any good polls, so the model defaulted to the national polling numbers, which benefited Trump. Hard to call those an upset.  Oklahoma, though, is a big win for Cruz. The bigger prize for him, though, is probably the Carson dropout, which should boost him 5-10 points in states with strong evangelical populations (too bad most of those have already voted).

Does this change the outcome? Right now, not according to our model.  We’ll have another post before the Saturday votes, but playing with the numbers still shows a high likelihood that Trump wins outright in the May/June timeframe.  Florida and Ohio will be absolutely critical to the “block Trump” faction of the party…and, of course, whatever it is that Romney has to say may still have an impact.

GOP Insiders Hurting Rubio, Selves

At a dinner following the South Carolina primaries, a GOP insider close to Jeb Bush said party leaders were looking for ways to get Cruz and Rubio to better cooperate in order to stall Trump’s march to the nomination.  The insider rolled off a number of options, including possibly stacking up a POTUS-VPOTUS ticket in exchange for a drop out.  A plan B, they said, was to get sufficient cooperation to force a brokered convention, at which point they could move the delegates in the right direction.

With Bush and Graham saying the party is “batshit crazy,” you’d think the establishment would be looking to save the party.  You’d be wrong. While Jeb will eventually endorse Rubio, GOP insiders say he still seethes at both Rubio’s decision to run and his personal attacks against Bush; Bush won’t offer that endorsement until the last minute.

The situation invites the question as to whether they consider Rubio a true “establishment” candidate. They shouldn’t, and it appears they don’t. Insiders are not actively pushing Kasich to drop out, reportedly in hopes that he can become the nominee in a brokered convention.

These insiders have better data than we do, but unless their data is wildly different than ours, they’re suffering from a bout of wishful thinking.  No one will drop out before Super Tuesday, and Rubio and Kasich will probably stay in through March 15, when Florida and Ohio vote in winner-take-all primaries.  The problem is, Trump is leading polls in those states, and will have a yuuuge delegate lead before March 15.

The chart above is based on state-level polls with state-level delegate allocation rules. After Super Tuesday, Trump should have around 440 delegates, Cruz 192, and Rubio 112.  Those projections would have Trump on pace to wrap up the nomination before May 1, with Cruz and Rubio getting just over 300 delegates a piece.

We’ve run dozens of projections based on current polling data[1]Of course, none of them involve Cruz or Rubio dropping out. We’ll need to check the 2nd preference votes for both of those candidates.  We haven’t seen good data since before Iowa.  At that time, nearly 30% of Rubio’s supporters went to Cruz and 10% to Trump.  Cruz dropping out meant 30% went to Trump and around 20% each to Rubio and Carson..  The only scenario that produces a brokered convention involves Kasich dropping out before Super Tuesday and 85% of his supporters breaking for Rubio.  Even then, Trump falls only 21 delegates short.

So let’s assume no one drops out until after Ohio and Florida vote.  What happens then? No surprise, Trump wins, needing only around 300 delegates more after March 15:

Kasich drops out after (losing) Ohio (to Trump). Trump wins the nomination.

So where does this put us? Barring massive shifts in polling numbers[2]Or, Ohio and Florida’s winner-take-alls bouncing to another candidate, GOP insiders will be out of time to affect the outcome if they wait until after Florida to shape the race.  They’re probably too late already; their unwillingness (or inability) to do so before Super Tuesday probably cemented the deal.
