It's not in Trump's nature to do the work, but all he has to do is sign the bill. It's staffers that do the work.
In 2016 the staffers were mostly Bush people, and the 2016 presidency was mostly a Bush repeat.
In 2024 the staffers are going to be much different. If Trump gets a trifecta all bets are off -- we'll get policy set by whoever gets Trump's ear.
