The GOP destroyed the party by caving to liberals instead of listening to their supporters.
Will is playing a very dangerous game here. Trump will be nominated, I believe. If, during the campaign, Will and others carry out their threat to actively work to oppose the nominee of the republican party, he may bring on total war, with Trump supporters attempting to turn out republicans up for election.
Will is playing with fire, and assuming Mr. Bowtie hasn’t gone completely senile and can still be reasoned with, those with sway over him ought to talk some sense into his increasingly pointy little head.
