I don’t think all Republicans agree with what happened with Trump trying to overturn the election.
something like 1/3 will not find fault with anything Trump did or does. they are cult members. they will say no one cares about Trump’s attack on democracy. They think trump made a big perfect call.
something like 1/3 don’t follow the news much and don’t like Biden. If they watch the hearings they might see what was going on and see Trump and his inner circle were at minimum morally guilty of trying to commit criminal conspiracy to obstruct Congress and defraud the United States even if Trump may not be criminally charged. if they listen to anything news related, they may only listen to right wing radio and never watch the hearing and what has been presented. they will say inflation, crt, crime, border issues, trans issues, are more important than the hearing because trump will not be criminally charged the hearings are a nothing burger.
about 1/3 of Republicans see Trump for what he is and they are losing their party. Conservatives who respect the rule of law like Cheney are being pushed out to make room for people people like Marjorie Taylor Greene and Gohmert and others. they understand that democracy is fragile. they expect an orderly transition of power.
