Today's the day. The GOP candidates are spread across the country, vying for last-minute votes in the 10 states holding primaries today. The biggest Super Tuesday trophy: Ohio, where polls show Mitt Romney with a slight lead over Rick Santorum. Both frontrunners made closing arguments there yesterday, trying to connect with blue-collar workers, a group Romney has so far failed to woo. Newt Gingrich is expected to cruise to victory in Georgia, the biggest state voting today, while Romney is supposed to easily take Massachusetts, Vermont, and Virginia. Ron Paul is aiming for Alaska, North Dakota, and Idaho. Tennessee is neck-and-neck, while Santorum leads in Oklahoma.
