There has been a complication. The intended site for the debate has a union picket line, currently. Dems will not cross a Union picket line. So something needs to be worked out for this upcoming debate to be held.
3 old white men (1 of which is a Democratic Socialist), 1 young white gay man, 2 women (one extremely progressive, one moderate), and one young man of color (yellow). That is pretty diverse, but maybe not diverse enough, as there is no black candidate (i.e., Cory Booker) or Hispanic candidate (i.e., Castro) qualified for this debate.
In the seemingly unlikely event that anyone gives a damn about the debate last night. I will report that they all did fine. The big winner was a debate format that had 7 participants instead of 11. It was much better functionally than trying to do it with 10 or more.
All of the seven are still magnificent in comparison to the metaphorically fecal ridden character of the now impeached Donald John T rump.
