Former House Speaker Newt Gingrich has lost his once-massive lead over rival Mitt Romney among Republican voters, according to a new poll, which reports that Gingrich slipped over the last ten days from a 14 point lead over Romney into a statistical tie.

“After enjoying 14- to 15-percentage-point leads over Mitt Romney in early December,” Gallup reports today, “Newt Gingrich is now statistically tied with Romney in national Republican preferences for the 2012 GOP presidential nomination: 26% for Gingrich vs. 24% for Romney. This follows a steady decline in support for Gingrich in the past 10 days.”
