Rick Santorum had been expected to win Louisiana's Republican presidential primary Saturday, but the size of the victory was a surprise. The former Pennsylvania senator captured 49 percent of the GOP vote. Mitt Romney, who is the front-runner nationally, finished a distant second with nearly 27 percent. Santorum sees his win as evidence that the party still has big doubts about Romney.

Among those who voted for Santorum was 54-year-old Curt Thurmon in Shreveport.

The U.S. Supreme Court is set to begin hearing oral arguments Monday in a Republican-led challenge to the national health care law that has convulsed the country and its political class for more than two years — and may well define President Obama's tenure in the White House.
