Mitch is going to pull it off
Best shot at holding his majority is to shut it down without witnesses, then hope that the vast hoards of cash that will flood in from oligarchs and corporations- foreign and domestic- and his RW media machine will be able to expand the political circus, and for long enough to divide and conquer. And of course don't need to shout to any foreign powers that he's intentionally left the back door open and the light on.
Although it is going to take The Greatest Show on Earth X 10 to pull it off. And I imagine that the steady flow of incriminating information that will continue post-kangaroo can be contained. You ain't seen nuthin' yet.
Looking forward to the post exoneration State of the Union. If GWB thought that the inaugural address was "some weird ####", just wait.
