Mitt Romney won in six of 10 Super Tuesday states but managed only the narrowest victory over rival Rick Santorum in all-important Ohio, an outcome that leaves open the Republican contest for the nomination to challenge President Barack Obama. Santorum, the former senator, captured three states and Newt Gingrich, the former speaker of the House of Representatives, notched a victory in Georgia, the state he represented in Congress for nearly two decades. The mixed results in the 10 state contests held on Tuesday suggest that Romney, despite padding his lead in the tally of delegates who will pick the nominee this summer, is still unable to win over the Republican party's most conservative elements. Regardless, said Eric Cantor, the No. 2 Republican in the House of Representatives, Romney has proven himself as “the only candidate in this race who's got a plan to turn this economy around.” Speaking on CBS television Wednesday, Cantor's remarks mirrored those of voters who told Ohio exit pollsters that the improving economy remained their chief concern.
