Hannity and Jeaninne both chose poorly. Hannity only cares about his advertisers.

Sean has a knack for poor choices.

Sean Hannity chose Moore blindly because of the R, the swamp, and what he knew about Moore prior. He moved heaven and earth to get Moore on his show the next day to exculpate him, clear his name.
The only reason Sean softened his tune after interviewing Moore is that Moore was lying to him and Sean could tell. He interviews people for a living and he has a pretty good judge of character or truth telling.
I am sure Sean is rooting for Moore to win, as am I, for seat purposes. Also we are probably both assuaged by there being no evidence Moore sought out any age females since getting married.
