Dems Still Frantically Trying To Stop Debates

I take it that the conventional wisdom is that the Biden-Wallace team did better than Trump...and apparently the next moderator is a ringer too... So why are Dems still trying to stop debates? Certainly not for the reason they profess--Trump is too mean. I mean, he's worse than most, but the debates are usually a shitshow. I haven't watched the whole thing yet, but from what I saw, Biden was worse than Trump. I mean, Trump was Trump...but Biden was the New, Progressive Biden: basically nonstop lies and character assassination. That's way worse even than Trumpian crackpottery.

What do the Dems know, I wonder?
