The Republican presidential race appears headed for the long haul after the “Super Tuesday” slate of primaries failed to produce a decisive winner. Mitt Romney won six states, including what appears to be a slim victory over Rick Santorum in the main battleground state of Ohio. Santorum, meanwhile, won three states, while Newt Gingrich won his home state of Georgia. Romney currently enjoys a sizable lead in delegates, but still only has a third of the number needed for the nomination.
