Rick Santorum's definitive win in the Louisiana primary on Saturday shows that the race to become the republican candidate for president is not yet over. Santorum won 49% of the vote; Mitt Romney came in second with 27%; Newt Gingrich was third with 16%; and Ron Paul received 6%.

Though his win in the conservative Southern state was Santorum's best showing date, it does little to change the overall delegate count, in which he trails Romney by a signficant margin. It does give Santorum some momentum going into the next contests in Wisconsin and Pennsylvania, which he must win to keep Romney from taking the nomination.
