I disagree with that statement. His new campaign team is trying to get him to stick to the script, be more presidential, etc. but he just continues to be a loose cannon. He's such a narcissist that it doesn't matter if there are other republicans trying to steer him toward reasonable policies. If he wants to build a wall, and Paul Ryan is telling him it's a dumb idea and he should focus on something else, he'll just get rid of Paul Ryan. I'm sure there were reasonable people in the Baath party, doesn't really matter if the guy at the top is a maniac.
The only republicans I would trust are the ones that have gone on record saying they think Trump is bad for the GOP, like Jeff Flake and Evan McMullin and ..
