Trump’s lead has eroded from 32 percent in early September to 24 percent after the second Republican debate, while Fiorina jumped from 3 percent to 15 percent, according to a new CNN/ORC poll.

In third place is Ben Carson is at 14 percent, while Marco Rubio jumps to fourth at 11 percent followed by Jeb Bush at 9 percent.

“I’m a little surprised,” Trump said of his drop on CNN’s “State of the Union,” “because other polls have come out where I’ve actually picked up after the debate.” An online Drudge Report survey found Trump won the debate, but this was the first scientific national poll after the big contest.

Trump also blasted Fiorina saying she “did a terrible job” at the helm of Hewlett Packard. “She’s got a good pitter patter, but if you listen to her for more than five minutes straight, you get a headache,” Trump said on ABC’s “This Week.”
