The party itself probably dislikes Trump since it paints all of them in the same light. However, Trump's voter base eats all of it up and they are the ones who typically do vote. It's pretty disappointing at the number of people who've come out of the woodwork since Trump's inauguration that are just the most repulsive people I've ever seen. This is not to say everyone who likes Trump is a hateful person, they aren't, but I just think hateful people tend to like Trump.
I don't think Trump is much for backdoor meddling. He's too proud and needs to toot his own horn all the time.
