This pretty much says it all:
Even so, McConnell matter-of-factly endorsed Trump when it was clear the real-estate mogul would win the nomination, a stark contrast to the continuing deliberations by House Speaker Paul Ryan. McConnell sees no political percentage in Republicans trying to disassociate themselves from the presumptive nominee by saying they won’t vote for him.
“I think that would be a mistake,” McConnell says, “because, obviously, you would like the people who are voting for your candidate for president to vote for you.”
With this guy, it’s all about getting people to vote for you. What you have to do in order to get that vote is almost completely irrelevant. (Perhaps the word “almost” doesn’t even belong in the previous sentence.)
Donald Trump is the culmination of this philosophy: a man who stands for absolutely nothing (except, in Trump’s case, selling the perception that he is a Tough Guy).
He and McConnell are made for each other.
