Despite his attempts at faking out his constituents into thinking he's not a Republican, Louisiana Congressman Joseph Cao still remains vulnerable. In fact, according to this article in the Washington Post that ranks the "five seats most likely to change hands after next year's elections", Cao is basically toast.

1. Louisiana's 2nd (R): Rep. Joseph Cao (R) isn't coming back to Congress in a New Orleans area district that gave Obama 74 percent of the vote last year. The real fight is for the Democratic nomination.

On a down note, the article also thinks that the second seat most likely to flip be another Louisiana seat.

2. Louisiana's 3rd (D): Senate Democrats' gain is House Democrats' loss when it comes to Rep. Charlie Melancon (D). Melancon's decision to take on Sen. David Vitter (R) in 2010 leaves open his seat in a southeastern Louisiana district where Obama won just 37 percent of the vote last November. Natural Resources Secretary Scott Angelle is seen as the 800-pound gorilla in the race, and if Democrats can get him to run under their banner, they could have a shot at holding the seat. (Angelle is considering the race but hasn't announced whether he would run as a Democrat or a Republican.) No matter what happens, this is a very tough hold for Democrats.

That's bad news because that's the seat that Democrat and lawyer Ravi Sangisetty is rumored to be running for.
