“Regardless of what Trump does post-presidency, his impact on the conservative base has been profound. According to one poll, 70 percent of Republicans don’t believe the 2020 election was free and fair. That’s not all that surprising considering the leader of the party is telling his followers that the process was rigged and illegitimate. So whatever direction the GOP goes, they’re going with a Trumpian base and that might be the defining constraint for the party over the next four years.”
