My concern is MSM is right and he's a monster. My favorite thing about his last term was that he had no institutional support so was hamstrung attempting to get anything done. That's how achieving consensus should be.
Now he leads the party and the party is in control of the house and the senate. If he was honest when he was campaigning, it could be a good thing. If was being dishonest, we're in trouble.
I'm also concerned that he'll be assassinated if he manages to get us out of our wars. While I like JD Vance on the surface, and feel a kinship to a self-made millennial with addict parents, his laugh and speech cadence are too guarded for me to feel confident in my opinion of him.
If he isn't assasinated, I'm concerned our intelligence agencies will find creative ways to keep him in our wars.

I'm hopeful RFK will rid us of the corruption in our health agencies. I'm hopeful the bureaucracy will be reduced and we'll all be a little more free.
