Ohio allocates its 66 presidential delegates proportionally so it’s unlikely that any candidate will achieve a decisive advantage in that realm. But of all the primaries left on the calendar, none carries quite the same symbolic weight as Ohio, a premier general election battleground at the center of the industrial Midwest.
Public and private polling suggests the race here is a competitive fight between Romney and Rick Santorum. Quinnipiac University gave Santorum a 7-point lead over Romney earlier this week. Private polling conducted for Republicans outside the presidential race, and shared with POLITICO, showed Santorum up by 5 percentage points.
