Mitt Romney is angling to solidify his front-runner status and Rick Santorum is fighting to keep it a two-man race as voters in 10 states put Super Tuesday's imprint on the Republican presidential race. Newt Gingrich just hopes to keep his struggling campaign alive with a strong showing in Georgia.
With Ohio looming large in the Super Tuesday lineup, textbook editor Heather Froelich outside Columbus gave her vote to Romney, saying: "He understands the economy."
Enthusiasm was in short supply among some of those casting ballots.
Gingrich got a reluctant vote from Tricia Tetrault, in Edmond, Okla., where she explained her decision this way: "Ronald Reagan wasn't available any more. What can I say?"
Santorum got the support of contractor Matt Howells in suburban Cleveland, but Howells didn't expect his ballot would count for much.
"I really don't see a Republican winning the White House," he said.
With 419 delegates at stake around the country, Tuesday's voting represents a sizable slice of the 1,144 needed to nail down the GOP nomination.
Romney, who turned back Santorum in a close contest in Michigan last week, hoped to continue his winning trend. He has won four consecutive contests, including Saturday's Washington caucuses.
