Louisiana

There's a chance for Democrats to pick up one House seat in Louisiana this year, but they're at risk of losing another one. Freshman Republican Ahn "Joseph" Cao faces an uphill battle for re-election in the heavily Democratic 2nd District, which includes New Orleans. In the neighboring 3rd District, the Republican nomination won't be decided until an Oct. 2 runoff, but the GOP appears to have an edge in the race to replace Charlie Melancon, the only Democrat in Louisiana's congressional delegation. Melancon is giving up his seat to run for Senate against Republican incumbent David Vitter.Louisiana has no governor's race this year. McCain won Louisiana in 2008.
