Maybe, but I will count on Trump, associates or family to keep it as a supporting role in the play.
I would think that Trump is still in the “bad news still puts you on the news” mode, but eventually the ones on the fence will realize Trump is not to be trusted. As many more already did figure it out.
I really hope Clinton, during the debates, makes as many references as she can stating that Trump pays no taxes and hasn’t in decades. He’s a deadbeat. That resonates with everyone. If he isn’t going to release data to the contrary, then she should just assume that he pays no taxes and state it as a fact.
