Charles Boustany and Jeff Landry is headed to a December runoff. U.S. Reps. Steve Scalise of Metairie, John Fleming of Minden, Rodney Alexander of Quitman and Bill Cassidy of Baton Rouge had no well-financed opposition seeking to unseat them, giving them largely free rides to new terms Tuesday. But Landry and Boustany were merged into the same congressional district when Louisiana lost a House seat after the last federal census. Three other contenders were in the race, and neither congressman was able to win outright in the five-person field. The runoff will be Dec. 8. Meanwhile, as expected, Republican presidential candidate Mitt Romney easily won Louisiana’s eight electoral votes against President Barack Obama.
