A new Quinnipiac poll in Ohio shows Rick Santorum with a slim lead over Mitt Romney, 35% to 31%, followed by Newt Gingrich at 17% and Ron Paul at 12%.
Said pollster Peter Brown: "At this point, the Buckeye State is too close to call and is clearly a two-man race between Sen. Rick Santorum and Gov. Mitt Romney. A third of the electorate say they still might change their mind. With five days until Super Tuesday, they certainly will be exposed to enough negative television ads to provide fodder for those who might want to switch -- or switch off."
A new Rasmussen survey shows Santorum leading Romney by just two points, 33% to 31%.
