You are aware, of course, in your piece of ownership of this mess, right? Had the Dems run literally 99.999% of eligible/qualified candidates we would not have Trump as the President today. Had you supported Bernie he wins by 7:00 EST election night, had Biden run it may have been the largest margin of victory ever recorded, had you run nearly anyone buy Hillary you win by a wide margin.
It was really only Hillary you couldn't beat Trump with, I only qualify it with "almost anyone but" because I am sure in the diluted world you live in you could make a case that Satan himself was eligible to run and that the right would have voted for him when in reality what I am saying is had you run anyone but Hillary we wouldn't be in this mess.
You own at least a portion of the problem because the right who still had some traditional values left was willing to let you Dems eat away at them and slowly destroy the country that was founded on those very values. It was happening right before our eyes and the right was letting it happen, accepting it slowly, but it was too slow for you so you went for the kill shot, and, finally, the right had all it could take.
Trump is a disaster, anyone with eyes can see it, but for Dems to not accept part of the blame for his presidency is myopic beyond belief.
The only good that will come of this four year setback is that the Dems, like it or not, will realize that they can't just get away with whatever they like and there will have to be some accountability of their choice of candidates going forward. That will ultimately be a good thing assuming the damage can be controlled under Trump. That's a 50/50 proposition, much like the blame for why he's our sitting President.
