I agree: but it won't happen until or unless the Republicans begin feeling, or fearing, repercussions at the ballot box. We need leaders who can rise above strictly political concerns in favor of the country. McConnell and Ryan are cowards; they've forfeited any claim to integrity, still less to courage. McCain has waxed and waned, but the trajectory of his career has always leaned toward integrity and courage; we need that from him now more than ever. Romney spoke the truth about Trump during the campaign, and then groveled to him in hope of becoming Secretary of State. He'd have been a good one, and I even believe that it was the desire to serve honorably that caused him to grovel to Trump. It was, however, a horrendous mistake. Trump neutralized him, neutered him, emasculated him -- invited him to dinner and served him his own testicles. I don't think Romney has a credible voice now; I'm not sure he ever will again.
Yes, I think the impeachment apparatus is being cranked up.
