Rick Santorum’s 22-point margin of victory in yesterday’s Louisiana primary was the 2nd-largest in any GOP primary this year — and was the largest outside of any candidate’s home state. Santorum received 49 percent of the vote in the Bayou State, equaling the combined tallies of Mitt Romney (27 percent), Newt Gingrich (16 percent), and Ron Paul (6 percent). Prior to the race, polling had shown Santorum up by 12 to 14 points.
The 22-point margin was Santorum’s biggest in any primary to date, and it surpassed Mitt Romney’s largest margin in any state except for his home state of Massachusetts. (Candidates have, however, posted larger margins in some caucus states.) Outside of the candidates’ home states, the largest previous margin of victory in this year’s primaries was Romney’s 20-point win in Arizona.
Exit polling in Louisiana showed that Santorum did slightly better among women than among men. Among women, he won 50 percent of the vote.
