Impeachment is just for PR.
Conviction in Senate unlikely.
Joe is only going to get the 25th if he has a stroke or something - - otherwise they are content leading him by the hand and running the country in his name behind all of our backs.
Only reason they let the 25th happen or impeachment conviction succeed is if they want Joe to step aside and he refuses. I seriously doubt they would let the GOP get even the appearance of a 'win.'
