What’s the deal with this McCarthy fellow that makes him unacceptable to both the 20 Republicans and all of the Democrats?

He is known by members on both sides to be very stupid and very weak. 

But honestly that's probably not why the 19 lunatics reject him. They reject him because, as much as he is willing to do literally anything to be in proximity to power, he isn't one of them. He isn't a genuine fascist lunatic, he just plays along because it helps him stay relevant.
