Romney wins key state of Ohio
Republican presidential frontrunner Mitt Romney scored a razor-thin win in the hard-fought presidential primary Tuesday in the Midwestern state of Ohio, major broadcasters projected.
The former Massachusetts governor had 38 per cent of the vote compared to 37 per cent for leading rival Rick Santorum, with more than per cent of precincts counted in the most closely watched of Super Tuesday's 10 state contests, DPA reported.
With a more populist style and making strong appeals to social conservatives, Santorum emerged in February as the top rival to Romney.
As a former US senator from the neighbouring state of Pennsylvania, Santorum was able to parley his new-found momentum into a lead in Ohio. As recently as February 29, Santorum held an edge of 34 per cent to 26 per cent over Romney in the RealClearPolitics.com average of Ohio polls.
A barrage of political advertising by the well-funded Romney campaign and his political allies may have helped close the gap leading up to Tuesday's vote.
"We went up against enormous odds," Santorum said earlier Tuesday, "not just here in the state of Ohio - where who knows how much we were outspent - but in every state."
