In my humble analysis “moderator” Chris Wallace did seem to have his thumb on the Biden scales a bit. Some of his questions to Trump seemed right out of the DNC playbook... on race, climate change and taxes... all were of the “have you quit beating your wife?” variety.
When Wallace sorta pressed Biden on his “Green New Deal” position, Biden dodged... Wallace let him escape. Seemed Old Joe was for the Green New Deal before just a few sentences later... he was against it. On violence in “Blue” cities... Biden was tepid at best in his condemnation.
The question about Trump’s taxes was particularly revealing since that story was intentionally released by the NYT just prior to the debate. It was a tactic designed to hurt Trump and Wallace was happy to use it. In effect he was a pawn in then NYT’s scheme to get Trump.
For that alone, Fox should fire him.
