He never needed any, because THATS NOT HIS JOB. His job is to entertain, and he does that. His show isnt "Meet the Press". He gives us exactly what he is supposed to. His show is so lightweight, I am surprised he still wears a suit and tie on that show.

His job is to also know his audience and Fallon's audience is overwhelmingly white and male. Trump voters.
