I'm with him 100% on the first bit - at this point, the single most important thing the Dems have to do is stop bickering.
As for the rest, at this point I don't even much care. I can see arguments both for and against in both directions - either choice is going to involve some risk but either choice can be made to succeed.
So the important thing, and really the ONLY important thing, is to pick one and run with it. Stop with the dilly-dallying and the second-guessing and the bitching and moaning and hand-wringing and make a choice and stick with it, so we can focus ALL of our attention on pounding those fucking fascist traitors' dicks into the dirt.
I wonder if he'll be thinking about the irony of having said that when Trump is in office, democracy is dead and he's plummeting 20 floors to his death after one of Trump's operatives has thrown him out a window.
