What is the RNC's doomsday plan?

They don't have one, and they can't stop Trump. They just have to hope that he implodes. If Trump actually wins the nomination, the Republican Party will actually just get worse (just like Goldwater pushed the party to the right, Trump will push it in a different direction). They will become a protectionist party, centered around nationalism and nativism. No longer a party of big business, but a party that serves the interest of the native population and its 'national interest' abroad.

"Worse".

That's my opinion, but yes its the worst possible direction to take electorally. The young, urban, black, Hispanic, Asian, non-religious, etc. All groups that are growing in the electorate and/or in population, are going to overwhelmingly reject the Republican Party (even more than before) and its going to keep losing.

The fact is that Mitt Romney would have had to do 45 points better with Hispanics to win in 2012 as opposed to just 4 points better with whites. So what's the strategy to entice asians, blacks, hispanics, and atheists into a political party that the overwhelming majority of them instinctually fear and loathe?

Yes, much worse.

Interesting to see so many on a supposedly centre-left forum standing up for corporatism over representative democracy.

Let's say it's June 2016 and after a long primary battle it looks like Donald Trump will in fact win either a majority or a strong plurality of delegates. Does the RNC have a plan in place to either try to deny Trump the nomination outright or minimize the damage to the party in this scenario? Does Reince Priebus have people working up a "doomsday plan" right now to respond to a Trump win?

Is there any way the RNC could wrestle the nomination away from Trump at the convention?
Would they try to force an unwanted running mate onto Trump's ticket?
Do any major establishment players back some kind of mainstream conservative third party ticket (knowing this will lose Republicans the election but possibly minimalize down-ballot damage)?
Would most sitting Senators and Governors bite their tongues and endorse Trump, or would many refuse to do so?
Could any state parties refuse to give Trump their ballot line? 

Doomsday would be denying Trump the nomination.

In the end, that's what I think will happen, but it will be so ugly as to damage the GOP brand in a year where it has a chance of upgrading itself.

There are options.  Individual state parties could name GOP electors not pledged to Trump, but that would probably be only an option in the South and Mountain West, where Trump would probably be strong.  In the Northeast and Midwest, the GOP would be up against it a bit more; those who would be handicapped by Trump in the GOP would probably have to fall back on making statements like "Well, I'm voting the National Ticket, but I'm only campaigning for myself."

I can't emphasize enough how ugly it would be if Trump doesn't implode, but he's denied the nomination if he's the leading vote-getter amongst the GOP field.  I don't know that the GOP could get Trump's supporters to vote for the GOP ticket under those circumstances, and some of them may well actually vote for Hillary to spite Trump's enemies within the GOP.  I am sure that the GOP will do everything to try to stop Trump's nomination, but at a certain point, doing so is worse than living with Trump.

The RNC should do what it takes to deny Donald Trump the GOP nomination because Donald Trump is not a real Republican.

If your party registration lists you as a Republican, you're a Republican.
