If Trump surrounds himself with incompetent advisors who have little interest in collaborating with even a Republican dominated Congress and proposing initiatives that can be readily challenged in court, it may tie up a large measure of plans that are beyond purely executive authority, nullifying the worst aspects of a Trump presidency. And if he is sufficiently at odds with an oppositional Congress, he may reflexively veto measures they pass.
I would love to see Trump stick to his guns to aggressively pursue Congressional term limits, this would put him immediately at odds with his political base in the legislature. Sadly he will cave to the establishment on this, so it seems. Trump voter's should be pissed if he starts walking back these "tear the system down" type promises.
So you should be hoping his advisors are Sarah Palin, Ted Cruz, Chris Christie, Forest Lucas, and others who are unwilling to compromise, and fraught with scandal and conflicts of interest. You should be afraid if he appoints manipulative more intelligent advisors like Mike Huckabee and Newt Gingrich who know how to work the political system and get their agendas through Congress while pacifying Trump in his worst tantrums. In that case, so much for being "the maverick outside the system"; he'll just be a mouthpiece for the Heritage Foundation agenda that Gingrich started advancing twenty-odd years ago.
