The GOP isn’t dumb- they are a bunch of wussies who got used to raking in millions while on the “defensive” aka minority mode. They care more about their vacation homes and fancy dinners than they do about this country. Donald Trump was the shot of testosterone the GOP needed. He is a leader- not a follower and not a coward.
Republicans controlled the legislative and executive branch after they promised on their mother's grave that they would repeal Obamacare. What did they do? They found every excuse why it couldn't be done and never did it for various lame reasons. Nope, the GOP is irredeemably corrupt.
