Trump's problem is he is truthfull. A real politician would say " I will definitely not contest the election results." Then afterwards, if they lost, they would contest the results.....LIE. Just like most of the other candidates that signed the pledge to support the primary election winner. Chickenshit bastards. You haven't heard much about that, have you?
I don't think I would call Trump "truthful", speaks his mind yes, truthful no.
It'll be a very interesting four years if he does get elected, I can imagine both sides of the house being at odds with him thru out his term.
