It depends on how much malignant Trumpness is still around in 2024, or if it ends up regressing back to some sort of tea party vibe with added nationalism. Regardless, the GOP primaries will still be the world's foremost collection of ghouls.
I could see Rubio or Haley on the ticket in an attempt to appeal to demographics. Don Jr is the banter option, but is a genuine moron. The danger for them is they would clearly prefer to nominate a boring, generic white guy.
But after Trump, that's not going to cut it.
Long way to go.
