Rick Santorum posted another convincing win in yesterday's Louisiana's GOP primary, but still faces doubts over whether he can broaden his appeal to win the race.
The Republican presidential candidate said the race was far from over, recalling the naysayers who said Ronald Reagan was too conservative to win the nomination.
But the road ahead is difficult for Santorum, who's slogging it out a game of numbers to clinch the 1,144 delegates needed to clinch the party's nomination.
Santorum will win at least eight of the 20 delegates up for grabs, according to CNN. Going into Louisiana, Mitt Romney had 563 delegates to Santorum's 251.
At this point, it is very unlikely that Santorum, Newt Gingrich or Ron Paul can overtake Romney, with their only chance being to keep him from hitting 1,144.
If that were to occur, the nominee could be decided at an open convention when party officials convene this summer, but it remains a long shot at best now.
The candidates get a few days of breathing space before the next round of primaries on April 3 when Wisconsin, Maryland and the District of Columbia vote.
Louisiana Republican primary results:
- Rick Santorum 91,305 (49%)
- Mitt Romney 49,749 (27%)
- Newt Gingrich 29,655 (16%)
- Ron Paul 11,460 (6%)
