A new 30-second campaign ad from pro-Clinton PAC Priorities USA zings Republican presidential candidate Donald Trump on his laughable insistence during Monday night's debate that his "temperament" is his greatest asset.


"I think my strongest asset -- maybe by far," said Trump at Hofstra University, "is my temperament."

The ad goes on to show clip after clip of Trump losing his cool, talking about how he'd like to punch protesters in the face, bombing "the sh*t" out of ISIS and shooting people on Fifth Avenue.

"Donald Trump," the ad concludes. "Unfit to be president."
