Scott was doing much better than in the last debate, but this was embarrassing and will hurt him.
He specifically targeted Haley with a direct accusation about raising gasoline taxes by 10 cents a gallon. When Haley said she did so with the agreement to reduce taxes by a triple amount elsewhere, Scott went back to interrupting the answer every two to three words so that Haley's response becomes unintelligible to the listener.
