Its Official: Melancon Challenging Vitter

Louisiana Rep. Charlie Melancon (D) announced Thursday morning that he will challenge Sen. David Vitter (R) in 2010, setting up a key Senate showdown in the Bayou State.

While local media had reported that Melancon made a final decision on the Senate race in June, Melancon delivered his official announcement in a video e-mailed to supporters.

Melancon running for congress also gives GOP a big opportunity at pickup although LA is expected to lose congress race after redistricting.
