Republican U.S. Sen. David Vitter survived challenges Saturday from two GOP rivals who called his years-old prostitution scandal a stain on Louisiana, reaching a runoff against Democratic state Rep. John Bel Edwards in the governor’s race.

The Nov. 21 runoff will decide who follows Republican presidential hopeful Gov. Bobby Jindal into office, the winner inheriting leadership of a state mired in financial problems that both candidates blame on the term-limited governor. Jindal is now waging a long-shot campaign for the presidential nomination.
