Wallace does not want to be blackballed by the liberal establishment, where he is connected. He wants to be “in” with the “in” crowd. He can get those liberals on his show without hesitation.
Bet he has a huge spike with Rush on there. It is the only time I tune into his NeverTrump-orama.
Wallace and the other Fox main news people are all Dems and basically are there for a paycheck. Only the evening people are conservatives which subsidizes the daytime hacks like Mike Jr.
