Trump did what he could before he got into his own way. He lost his best chance because of his ego. Time to move on to someone with a silimiar vision sans the egomania.
He would rally every liberal, leftist, moderate Dem to the polls. His ego, arrogance and inability to be civil as President offended too many to ever win over a majority again. Nominate Trump and he'll divide the Republicans and the Dems will win.
At first he was interesting. But I find him too swayed by public reaction to the topic of the moment. I am not impressed - seems more a shell than a serious thinker with real ideals.
