What are the odds of a Mitt Romney nomination?

IIRC, the new RNC rules require the nominee to have won five binding state delegate contests. So, in an attempt to prevent the minor nuisance of a few Rand Paul delegates putting his name up for nomination, they may have committed themselves to picking between Trump and Carson as their only choices for a nominee. Delicious irony.

There is no way that Trump and Carson win 45 states combined.

a. That's not how it works. It's 4 * the number of other candidates subtracted from the number of binding states (which is less than 50 I believe). You're assuming 3 candidates.
b. I wouldn't discount the possibility.

Mark Halperin reported a rumor on this very possibility on his show today, and the Washington Post reported that there's draft Romney rumblings in the establishment.

Anyone who thinks a brokered convention won't happen... all it takes is three credible candidates to stop any one from getting a majority of the delegates.

I knew the Romney buzz would return eventually. The media is literally obsessed with the "potential late white horse candidate entry!" story that never actually happens. Gore, Biden, Christie, Romney...

It's almost as boring as the brokered convention and electoral college tie scenarios that are endlessly covered yet have a ~0.1% chance of actually happening.

GOP made a fatal error. They went with Jeb. Which gave rise to Trump. Now, they are rallying behind Rubio. Trump has the money to stay in and win the nomination, but lose the general.
