It's too late. There was only one shot at defeating Mr. Trump, and that was getting behind Mr. Rubio from New Hampshire on.
All this panic from the establishment at this point is just closing the barn door after the horses have already escaped (is that how the saying goes?), and is just doing pointless damage to the party.
Mr. Trump is going to be our next president, and as such he will have the power to reshape the Republican Party to fit his values. The Right might want to start dealing with that, because it's going to happen whether they like it or not.
It'll be much worse for the Left. They are going to be out of power for a good 20 years.
