No, I don't think Trump serves at the pleasure of the GOP. But, like it or not, he and the GOP are now tied to each other. My point is that having an incumbent president of your own party is an asset for members of Congress and Congressional Republicans may try to convince him to run again for that reason. Whether or not he acquiesces is anybody's guess.

But this is all speculation, of course. We've entered into the bizarro world of politics now, so who knows?
