I'd take issue with the 'committed' part. Many of his followers are using him as a pawn within the Republican ranks. There's little commitment on their part. Others, yes, they are committed Paulites.
The ones he has to get beyond are mostly in the first group. But part of the reason he isn't winning new support is that he isn't making an effort to get beyond those 'users'. On the contrary, he seems comfortable with the situation.
I’ll give you that, I agree. Unless I change it to ‘should be committed’?
