Paul RINO is irrelevant. He’s being Cantored. This time next year he’ll be peddling influence on Wall Street instead of Washington.
It’s most likely that Ryan will keep his seat, he has strong support in his district and those are the only opinions that count.
But it matters not with respect to Trump, because he will come in line. Part of the negotiating process is to give the other side an “out” and starting today, Trump has done that. Trump will never cave on the key points that his candidacy is built on. Read Art of the Deal if you doubt that.
