Yeah, as if overturning the will of GOP voters will allow them to win. First off, their voters would practically revolt - The final proof that the establishment is only in this for themselves and screws them every chance they get. They will see this as the establishment taking their chance at "winning" and flushing it because it may hurt their corrupt agenda.
Second, whoever they nominate will not only suffer from a severely split party and widespread resentment, but they start off with a significant disadvantage in cash and field infrastructure. They basically start out with nothing, except maybe a Super PAC filled with tens of millions of dollars from desperate billionaires. That won't be as helpful as one would like to think, seeing as the candidate would be just starting out with little time to catch up.
Terrible idea. If they wanted an alternative, they should have worked something out much earlier.
Trump never won the majority of Republican primary voters, not even close. The voters won't revolt (at least most of them wont), they're only going along with Trump now because he's the presumptive nominee.
Trump won with ~40% of the vote, which is the same percentage that Goldwater, Nixon, Mccain and Romney had.
Romney and McCain had around 50%.
But they didn't have to knock out the most divided field in presidential election history. And TRUMP got more votes in total than any previous nominee. Over 13.5 million (almost 45%).
