Trump isn't a republican. He is a huge middle finger to he DC elite. Always has been. These douche nozzles hate that the vast majority of Americans despise them. Pols don't appreciate that when you waken the sleeping giant you might have hell to pay. That is why non-politicians who don't play by the rules must be jailed.
Second place in the R primary is worth holding on to - high probability Trump is forced off the ballot by the machine. That could be on the national or local level, or some combination of both. Anyone who thinks Trump on the ballot is 100% in the hands of the primary process is naive.
If I could wave a wand and determine the result, I would run Burgam with Vivek as VP. Burgum seems to STFU and get to work making government smaller and more efficient. Worth giving Vivek a shot on the larger stage which can determine if he can get shit done or if he a pure grifter. Screaming "grifter" at Vivek is hilarious pot calling kettle black level stuff. Elites hate people who are successful outside of politics for playing in their sandbox especially if they are YOUNG and successful. Yuck, let me grift into my 90s and leave Congress feet first!
Republicans hide behind Trump's aura as excuse to dump him when they really want to get away from his policy. No war is bad for business. Look at them slobber over Ukraine. Smaller government is bad business. Less federal power is bad for business. Neutering the alphabet agencies is bad for business. Trump is in it for the game, he isn't serious about fixing shit. He hasn't articulated any plan, or any team to attack these issues. He just wants to suck up the limelight.
Screw Haley - war monger neo-cons need not apply.
