Romney wins 3 states; Santorum takes 2
WASHINGTON — Rick Santorum has won the Republican presidential primaries in Tennessee and Oklahoma.
Mitt Romney earlier won primaries in his home state of Massachusetts, Vermont and Virginia. Newt Gingrich has won in Georgia, where he represented a suburban Atlanta district in Congress.
Voters across 10 states are choosing among the Republican candidates on Super Tuesday.
Romney and Santorum are locked in a tight race in the key matchup in the Midwestern industrial state of Ohio. With 10 percent of the precincts reporting, they each have about 38 percent.
More than 400 delegates were at stake on the busiest day by far of the race to pick an opponent to President Barack Obama in the November election.
