Several weeks ago DU-folk were predicting that Trump was so scared of debating The SHREW that he would duck debating her at all. That prediction got crushed by reality, so I guess this is their next prediction.
At this point, the interesting questions are:
* What MSM persons will "moderate" the debate? At this point, the announced plan is for each debate to have one "Moderator".
* How openly and in what ways will the "Moderator" work against Trump? IMO, it's not a question of "if", but of "when", "how", and "how much".
* How will Trump respond to "Moderator" partisanship? Rs pretty much never have, but I think Trump would, and he might cut the right balance between calling out and confronting. Further, I don't think Trump would be deterred by a passive-aggressive victim-playing female "Moderator".
