The problem isn't Trump, especially now that fewer people are listening to him. Even the evangelicals, who still worship him, are ready to move on.
The problem is that there were no checks on having a lunatic as president. The Republicans loved the noise and distractions. They have learned how to keep Trumpism going, without Trump. 35% of the electorate is with them. They are trying to stop another 20% from being able to vote.
