According to Robert Reich[0], the republicans' whole plan is to use trump to ram through their unpopular agenda and then impeach him when he's no longer useful:
Him: They’ll get as much as they want – tax cuts galore, deregulation, military buildup, slash all those poverty programs, and then get to work on Social Security and Medicare – and blame him. And he’s such a fool he’ll want to take credit for everything.
Me: And then what?
Him (laughing): They like Pence.
Me: What do you mean?
Him: Pence is their guy. They all think Trump is out of his mind.
Him: So the moment Trump does something really dumb – steps over the line – violates the law in a big stupid clumsy way … and you know he will ...
Me: They impeach him?
Him: You bet. They pull the trigger.
