I get the impression that Powell is a little fed up with Trump.
And so is the president.
Obama Condemns Trump in Full-Throated Pitch for Clinton By JULIE HIRSCHFELD DAVIS
In Philadelphia, Mr. Obama appealed to young and minority voters while criticizing Donald J. Trump and coverage that had turned the race into a “reality show.”
I think it is personal with the president now over the whole birther/Muslim issue. And Powell confirmed it. It was nothing but a racist bigoted attack on the POTUS.
It is a disgrace that the Republicans are now stuck with the idiot.
Powell suggested in another email that even critical coverage of Trump didn't really work: "To go on and call him an idiot just emboldens him."
