I think there are very few Republican stars who are unhappy about this. There are several really great solutions to this equation* where you please Trump's fanbase, don't anger Trump, but don't actually create any barrier to Trump getting destroyed or get any more Trumpiness on you. You object to how Democrats shouldn't do this and shouldn't get away with it, but you don't say America is lost without Donald. You don't talk about whether he is guilty, just about the motives of the people driving it and how unprecedented and inappropriate it is. If you are reasonably careful, you can cover ALL the bases!
*Wolf Blitzer asked Mike Pence about it last night and poor, sweet Mike Pence said he's been travelling all over this nation thinking about his future (who know WHAT that could be. Probably a rock band, because I for one just cannot see how the guy who helped Trump get elected and THEN didn't "come through for him" on Jan 6 has ANY constituency) and it turns out that America just doesn't care about this. They care about their suffering from Biden's failed policies. This is just outrageous politics gone wrong. See? I did not say Trump is getting his reckoning, I did not leave him dangling in the wind, I didn't comment on his guilt or innocence or pay him any compliment, but I stood up for him when the chips are down. Now let's see if I can get this sucker in gear and ride it into the White House. He didn't say ANYTHING about Trump.
