NEW ORLEANS (AP) - The only Democrat in Louisiana's U.S. House delegation is thinking about running for the Senate, against Republican David Vitter.

Rep. Charles Melancon, a former sugar lobbyist from Napoleonville, says many people have encouraged him to run. He said he will announce his decision in coming weeks, after conferring with his family.

His statement was e-mailed Saturday by Bradley Beychok.

Melancon beat Billy Tauzin III in 2004 for the House seat previously held by Tauzin's father, Republican Billy Tauzin. He won re-election in 2006 against Craig Romero, and was unopposed last year.

He's a leader among the conservative Blue Dog Democrats.

Melancon says he has worked to be a bipartisan leader who doesn't let party politics get in the way of Louisiana's progress.
