At this point, GOP presidential nominee Donald Trump has said so many horrifying, vile, and stupid things that it is hard to keep track. It seems to be that the most recent verbal diarrhea that comes out of his mouth makes one forget the verbal diarrhea he said earlier. So, just to recap and to serve as a little refresher, here are 15 of Trump's worst quotes from throughout the campaign season.

1. On Mexicans crossing the border

“When Mexico sends its people, they’re not sending their best… They’re bringing drugs. They’re bringing crime. They're rapists. And some, I assume, are good people.”

“Donald J. Trump is calling for a total and complete shutdown of Muslims entering the United States until our country's representatives can figure out what is going on.”

3. On Former Prisoner of War and Senator John McCain

"He's not a war hero… I like people that weren't captured."

4. On Carly Fiorina's appearance

"Look at that face! Would anyone vote for that? Can you imagine that, the face of our next president?! I mean, she's a woman, and I'm not supposed to say bad things, but really, folks, come on. Are we serious?"

5. On Megyn Kelly moderating the GOP debate

“[Obama] founded ISIS… And I would say the Co-founder would be Crooked Hillary Clinton.”
