GOP gets ready to go 'nuclear' over Trump

A lot of people are asking a very obvious question about Mitt Romney 's big speech today blasting Donald Trump and warning all voters that he is simply not fit to be president.

They're asking why he did it. Because it seems like Romney's efforts will only help the Trump cause. Remember that Trump's entire allure to the voters seems to come from his open challenge to the establishment in both parties. And Romney's efforts will surely be seen as proof that the more and more unpopular establishment is frantic to stop him.

But that legitimate question ignores the fact that the said establishment is more than just frantic to stop Trump; it's becoming more and more willing to invoke an electoral nuclear option. And Romney's speech today could be part of laying the groundwork for such an option.

The strategy has three main stages:

  1. Lay a groundwork for major party donors and leaders to refuse to support Trump even if he wins a majority of the delegates.

  2. Get behind one of the remaining GOP candidates, and give him the financial support and enough political cover to run even as a third candidate in the November race.

  3. Play Electoral College math and hope that no one wins the required 270 electoral votes in November. That throws the election into the heavily GOP-controlled House and gives the presidency to the establishment-blessed Republican.


Sound crazy? Maybe, but if you don't think the Republican Party leaders aren't already on political DefCon 1 over Trump you're being naïve. And you're also being naïve if you think the above scenario, as crazy as it sounds, is beneath either party given an existential challenge like Trump. And it is an existential challenge because a Trump win doesn't just mean the established GOP will lose the White House again, it means the entire Republican Party will be ripped away from them probably for good.

Now let's get back to the electoral math, because it's the key to assessing whether this possible plan could actually work. History is always a good guide, and the last U.S. presidential election with three candidates who each won states in the general election occurred in 1968. That was when Richard Nixon won an extremely narrow election in the popular vote and held off Democrat Hubert Humphrey and Segregationist Democrat rebel candidate George Wallace in the electoral college.

But a closer look at the results state-by-state shows that Wallace came extremely close to throwing that election to the then-Democrat controlled House, where Humphrey or another Democrat would likely have been sent to the White House. Nixon took 301 electoral votes, Humphey had 191 and Wallace got 46. But Wallace only lost to Nixon by a hair in South Carolina, North Carolina and Tennessee.
