Edwin Edwards, the 87-year-old former four-term Louisiana governor who spent more than eight years in federal prison, has earned a runoff spot against Republican Garret Graves in the state's 6th Congressional District.
Graves and Edwards will face each other on the Dec. 6 ballot.
Voters' views of Tuesday's U.S. Senate election in Louisiana, according to the preliminary results of exit polling conducted for The Associated Press and television networks. Three of the eight candidates were considered major and invited to debates: Democratic incumbent Mary Landrieu and Republicans Bill Cassidy and Rob Maness, who was backed by the tea party.
The only Democrat in Louisiana's House delegation, Cedric Richmond, has been successful in his bid for re-election to a third term.
Richmond faced two other Democrats, Rufus Johnson and Gary Landrieu, along with Libertarian Samuel Davenport and independent David Brooks in Tuesday's election.
Richmond, who is the only African-American in the state's congressional delegation, first won the 2nd District seat in 2010, when, the district tied together predominantly black areas of New Orleans and neighboring Jefferson Parish.
Rep. Steve Scalise, who became House Republican whip this past summer after serving in Congress for only six years, has won re-election over three largely unknown opponents in Louisiana's 1st Congressional District.
Scalise faced Democrats Lee Dugas and Vinny Mendoza and Libertarian Jeffry Sanford in Tuesday's election.
Scalise first won the seat in 2008 when the previous incumbent, Bobby Jindal, became governor.
