CANTON, Ohio (AP) - Republican presidential candidates Mitt Romney and Rick Santorum are making last-minute appeals to Ohioans. Polls there show a neck-and-neck race just one day before the Super Tuesday primary.
Ten states across all regions of the country will hold GOP nominating contests Tuesday.
Romney has a significant advantage in northeastern states like Vermont and Massachusetts and Santorum sees advantages in conservative states like Oklahoma. Ohio is a critical battleground that also has a history as a key general election swing state.
