Without those pesky primaries to worry about and with Bernie once again out of the way, they have pretty much carte blanche to handpick their own ticket.
Shoving old Joe aside is child's play. My guess is that it's already worked out. When the timing is right, we will have a teary press conference in which Biden announces he has dementia and for the "good of the nation", he must step aside and let somebody else carry the torch forward. MSM will have days of wall-to-wall coverage of Joe Biden's wonderful 50-year career in the public sector.
Then...
As you called it. Should come with a barf alert.
I hate that point and smile and wave its all theater
