IMHO -- The "Mitch" that we saw before the Senate hearings began is softening as I was afraid. It still would take 20 GOP votes to remove him; but Bolton will do a lot of damage -- meanwhile you can bet that the Bidens will remain unscathed. Heck -- the MSM didn't even cover Bondi's shredding of the Bidens. The DEMS will find a way to avoid any testimony that involves the Bidens - count on it. Mitch and others will cave. No doubt about it.
Even though it's going to take 20 GOP defecting, I think we can count on Murkowski, Collins, Lee, and Mittens to vote to remove him...I think we'll see others.
