Well, according to Roger Stone they’ve got $75 Million of Koch money plus another $25M and if Rubio fails to win Florida, he’s done and it’s the nuclear option - steal the election at the convention and put in Romney.
There is only one sure way to preclude this and that is to get behind Trump and make sure he runs the table and has 1237 delegates. Then the GOPe are screwed.
Wonder how the Koch’s and the other GOPe mega-donors made their fortunes wasting hundreds of millions of dollars like they have on Bush and now on Rubio and possible Romney in an 11th hour run?
By the time Trump beats Rubio in Florida, Trump will likely either have or very nearly have already secured the 1237 pledged delegates needed to secure the nomination and prevent any brokered convention or other possible GOPe trickery at the convention from happening. Won’t matter if Romney runs in the late primaries or not by that point.
More likely scenario is that the GOPe will try to get Romney or some other establishment hack to run as an independent third party candidate for the sole aim of defeating Trump in the general and handing Billary the Presidency.
They might even get a jilted, Trump hating Cruz to run 3rd party on the Constitution Party ticket with the sole intention of taking enough votes from Trump to secure his defeat in November.
The GOPe could care less about winning in November - they know that if Trump prevails in November, that he will clean out the RNC offices and appoint all new RNC officials, especially a new chairman. Them keeping their jobs is more important than saving the country.
You underestimate the corruption of the GOP-E.
