I've long said that we need "Pop-Up Presidential Debates," after the old VH-1 "Pop-Up Video." In this type of debate, every time a candidate said something untrue, there would be an immediate "pop-up" on the screen saying "HE'S LYING" and giving the truth. Sounds like, if last night's debate had been a pop-up one, Trump would have been virtually obscured by the pop-ups.
