One would think with a 15+ month Presidential campaign we should know Where They Stand on the IssuesTM, especially the winner. But alas, it seems heartfelt policy positions are not really part of GOP President-Elect Trump's id nor were they of much interest to the MSM in the lead up to November 8th. What does he really believe? Is he a blank slate? Will he sign any bill that comes across his desk? Does he even know he can veto a bill? Who knows! He's just going to MAGA through winning, so don't worry your pretty little head.
I don't think Trump even knows. It's clear he never expected to win even the GOP Primary, much less the Presidency, and now here he is - a resentful narcissistic know-nothing blowhard who both craves approval but will lash out at anyone who disrespects him (at least in the moment).* The GOP congress looks at him and has decided that they can now pass their dream agenda that involves massive corporate and The 1% (or really the 0.1%) tax cuts while destroying Medicare and the Affordable Care Act (insert Dr. Evil laugh here, or maybe Vincent Price in Thriller). Plus SCOTUS!
OTOH, to the extent the GOP cares about the U.S. government and democracy beyond their access to power within that framework (and I have my doubts about how much there is there), they are playing a dangerous game with Trump, the justice system, his political advisers/cabinet appointments (a significant % of whom seem to be paranoid and/or believe in conspiracy theories), foreign policy, rampant corruption, and the national security state. Sadly, they are not likely to be the losers in this game.
And he's not even President yet....
