The number of general election voters who have a negative view of Rick Perry has jumped 9 points since the last GOP presidential debate on Sept. 7, according to Nate Silver at The New York Times’ Five Thirty Eight blog. Meanwhile, Perry’s average lead over Mitt Romney in polls has fallen by 3 percent, and he’s dropped four points in a hypothetical match-up against President Barack Obama. Experts say Perry’s campaign could be in trouble if he has another shaky performance tonight in Florida.
