I agree, emphatically. Let the Dems do their own damage, and destroy their own dangerous and virulently anti-American political philosophy.
Assuming Trump will win there are 2 issues/goals: 1) Make them eat each other by screwing Bernie again-points to Bloomberg as Biden is toast. 2) Help Trump take the biggest bite out of the black vote-points to Buttigeg. Rats would put a calming effect on their battles by picking Kornblache as vp.
