Voting ended at 7:30 p.m. ET across Ohio, where exit polls showed a tight race between former Massachusetts Gov. Mitt Romney and former Pennsylvania Sen. Rick Santorum.

The two campaigned throughout the state on Tuesday and hoped to edge out the other in the most closely watched of the Super Tuesday contests. Ohio is historically a bellwether state, so a victory here could give Romney a boost and place him further ahead of his competitors. Conversely, it could buoy Santorum's campaign after Romney's victory in the previous four primary contests before Tuesday.

Among the 10 states voting this Super Tuesday, 419 delegates are up for grabs, according to the AP. It takes 1,144 to secure the GOP presidential nomination.
