My personal guess is that the GOP is now the party of Trump. I'm not happy about that and I wish it were otherwise, but I think the future of this party belongs to the Kristi Noems of the world, with folks like Josh Hawley and Ted Cruz falling in line because they know that's where their bread is buttered. Folks like Mitt Romney are either just going to be along for the ride, or they'll be purged.
Right-libertarians like me just aren't going to have a political home. Not that I was ever totally comfortable with the Republican party anyway, but definitely not now.
I'd love to be wrong, but I honestly don't see a lot of reason for optimism. Republican voters seem all-in on QAnon, OAN, white identity politics, etc. and they'll pull their political leaders in that direction.
