Evangelicals are willing to ignore the personal morals because they like the court appointments. They'll back him.
Dems are in a real fix in 24. Biden will be too old, and no other centrist could make it through the primary. There are a ton of progressives who could easily get 170 electoral votes, but none who can get 270.
Which leaves Dems nominating a leftist and hoping people remember Jan 06. Not a solid plan.
My read is the conservatives have the courts. Although besides abortion I don't see any other wedge issues that gets folks fired up like saving babies. So they are going to keep pushing on the abortion issue, trying to outlaw it next at the federal level. Which means they are going to have to start winning hearts and minds in blue states... and I don't see how Trump is going to be useful toward that goal?
