Scalise easily beat three opponents, taking 75.3 percent of the vote in an election to determine a successor to Bobby Jindal, who resigned from Congress after his election in October as governor of Louisiana. Scalise, a Republican, will represent what the New Orleans Times-Picayune called a "decidedly conservative" congressional district.
Cazayoux, on the other hand is a Democrat who, with Saturday's victory, moved a House seat out of the Republican column with a 49.2 percent to 46.27 percent victory over Republican state Rep. Woody Jenkins. Cazayoux will succeed retired Rep. Richard Baker.
U.S. Rep. Chris Van Hollen, D-Md. -- the chairman of the Democratic Congressional Campaign Committee -- issued a statement saying Cazayoux won despite efforts by House Republicans to use "false and deceptive smears" in a $1 million campaign in a district that had been held by the GOP for more than 30 years.
