Rick Santorum's Ohio problem - in one chart The Ohio Republican presidential primary is less than 24 hours away. Widely considered the crown jewel of Super Tuesday, Ohio appears to be a toss-up between former Pennsylvania senator Rick Santorum and former Massachusetts governor Mitt Romney. But, one look at the chart below shows you why Santorum and his forces are starting to downplay the importance of the Buckeye State. "It's a tough state for us, only because of the fact of the money disadvantage," Santorum said on "Fox News Sunday" over the weekend. Can a candidate win with a trend line that has turned that sharply downward? Sure. And there is a new Suffolk University poll out today that shows Santorum leading Romney by four points. But, Santorum's sharp drop in Ohio polling has to be unsettling to his allies.
