Results from new poll of GOP primary voters from Democratic firm Public Policy Polling: Newt Gingrich (28 percent), Herman Cain (25 percent), Mitt Romney (18 percent), Rick Perry (6 percent), Michele Bachmann and Ron Paul (5 percent), Jon Huntsman (3 percent), Rick Santorum and Gary Johnson (1 percent). One particularly interesting note from PPP: “There’s reason to think that if Cain continues to fade, Gingrich will continue to gain. Among Cain’s supporters 73 percent have a favorable opinion of Gingrich to only 21 percent with a negative one.”
