Crushed by whom?
As POTUS Trump has no power over the RNC or individual congressman...
Remember he is running against the GOPe...not likely to make very many friends...
He can pressure them via the bully pulpit...but to actually make them do his bidding by force...?
Trump is not King...
My concern is can Trump govern, he's used to being the "BOSS" of his business having absolute final say...
Can he transition to governing ?
I don't think so..
You are missing the most important aspect of a Trump Presidency.
If, he wins and that is a big if,
he will carry into office the biggest mandate in American history.
Congress critters will fear him like they feared Reagan.
Let’s see Trump use EO’s. Why not? The useless Republicans didn’t stop 0bamao when he did it. It’s the new governing style.
