Romney gains delegates after Super Tuesday

Republican presidential candidate Mitt Romney has crowned a string of Super Tuesday victories with a win in the key swing state of Ohio. As expected, Romney won in his home state of Massachusetts, as well as Idaho, Vermont and Virginia. After a cliff-hanger count, he narrowly edged out Rick Santorum to take Ohio, the night's most coveted prize. Santorum won contests in three states, while Newt Gingrich took his home state of Georgia. Ron Paul was pinning his hopes for his only victory of the nomination campaign on Alaska's caucuses – though Romney took Alaska as well. The eventual nominee will challenge Barack Obama in November's election.
