If you tried to use historical context (the Johnson or Nixon impeachment)....the template wouldn’t really fit. I think Shifty and Pelosi already know that this is mostly a failed effort, and simply a game to run out the clock...hoping to get some public-gain from this.
As for the Senate receiving the ‘package’? I would guess that shortly before Christmas, it’ll occur. They probably won’t start the process there until the first week of January. If Shifty does a poor job in assembling this...the Senate could refuse to pick it up, and simply have a up-and-down vote to refuse the package. It’s still early to guess on that part.
I would suggest one thing....both Hunter Biden and Joe Biden are going to be dragged into some Senate hearing after the package is accepted, and both will likely refuse to participate. What happens after that is an unknown. I think in the end...Joe Biden will look like some 1920s criminal hoodlum.
He's got 80% of the press and a third of the public fully on his side. Who do you think the House managers will be?
