Your turn, Newt. Mitt Romney has a new companion at the top of the polls, and it’s former House speaker Newt Gingrich. In CNN’s latest survey of the GOP presidential field, Gingrich surges to 22 percent, just behind Romney at 24 percent but well within the poll’s margin of error. Meanwhile, CNN saw Herman Cain’s support plummet in the aftermath of harassment allegations, dropping 14 points, down to 11 percent. Public Policy Polling will also release similar findings today.
