I can pontificate why Trump can do it but the professional politicians can not do it. It is because the politicians depend on their sugar daddy rich donors to stay in the campaign. If the sugar daddy orders them to push Obamatrade, they are forced to acquiesce.
Trump on the other hand does not need sugar daddy's to stay in the campaign. He can afford to speak his mind. Others can't.
Exactly. Each one is bought and paid for. IRS, Benghazi, Clint’s email, Fast and Furious, and not a damn thing done but talk.
