I don't like him as a person, which is not unusual for politics. I voted for Clinton in 2016 because I didn't think Trump was serious about being President. But he did a better job than I expected, especially with the economy. If not for the pandemic, he likely would have coasted to a win in 2020. I voted for him in 2020.
That said, while I don't think he conspired to stage a coup, his actions after the election were embarrassing. He should have clearly stated, as many times as needed, that the rioters had to stop and let the machinery of government do its job. But his ego is too big and he pushed the 'stolen election' narrative at the worst time. I'd be more satisfied with his loss if the current administration wasn't such a disaster, but I think the party needs to move on from him.
But yes, I think the hearings are just political theatre, and I do think they are timed in the hopes of keeping it in the public eye all the way through to the midterms if possible, because the current administration has been a disaster. But it could be effective, since the best hope for the Democrats right now would be for Trump to keep the GOP split and fighting with itself over control of the party.
