The NRCC began airing an attack ad on Louisiana TV last night taking aim at Don Cazayoux, the Democratic candidate to succeed Rep. Richard Baker (R-La.). Cazayoux will face off against Republican newspaper publisher Woody Jenkins in the state's sixth district special election May 3.

NRCC spokesman Ken Spain told The Hill the ad would run for one week. To attack Cazayoux in the conservative-leaning district (it voted 59% for Bush in 2004), the NRCC tapped a traditional conservative issue -- taxes -- suggesting Cazayoux should change his name to "Don Tax You."

Cazayoux's campaign did not return calls for comment.

DCCC spokeswoman Kyra Jennings, however, told The Hill that other prominent Louisiana Republicans -- Rep. Rodney Alexander and first congressional district candidate Steve Scalise -- also supported the tax-raising bills cited by the NRCC's ad.
