Yeah, recently there was a vote to begin the impeachment process before Grandpappy Mueller ran out the clock, feigned incompetence, and looked physically weak and sounded mentally feeble. Regardless of whether you think it was totally an act, his brain is mush, or some combo of the two, that only got 95 votes out of 235 Democrats, and no Republican votes in the House.
You could hear the Trump Derangement Syndrome people saying things on CNN and MSNBC in game terms and sports analogies like, "Mueller needed to score some points for us. Mueller needed to run with the ball and he fumbled it." They thought Mueller was going to convince people to back impeachment. Instead, he's almost certainly soured people on it. I think Republicans and Moderates to a large degree bought the War Hero Super Hero Judge Dredd line on Mueller, and then seeing him turn in that "doddering" performance and the media all but cop to the investigation being ran by Weissman and his other cronies, his other "team leaders," shoots the whole thing to shit. If Robert "Hands off" Mueller was eating oatmeal and watching Bonanza reruns while a bunch of sleazy Hillary and Obama fixers were running it, the special counsel takes on a whole new dynamic. You've already got House reps and senators saying they are pissed that Mueller either won the Academy Award for Feigning Tactical Senility or really was mush-brained, and was ignorant either way about the investigation. I can't think of how any Republican is supposed to get on board with impeachment now.
