Trump would have gone full Reverend Wright on poor Barry.
As a result, the black GOP vote would have been at least halved, from 4% to 2%. The media would have melted down, in the process, getting out Trump's message free of charge (due both to the substance and form of Trump's presentation).
And President Trump would have been sworn in eight years early.
Did anyone hear Bernies victory speech last night? He showed his hand as to how he would fight Trump if he (Bernie is the nominee). He brought up the birther issue and suggested racism on Trumps part. Bernie loves those riots!
