Lt. Gov. Jay Dardenne is taking aim at gubernatorial rival U.S. Sen. David Vitter because he skipped a nonbinding Senate vote this week and held a campaign event with New Jersey Gov. Chris Christie in Baton Rouge.

In a statement released by his campaign, Dardenne noted that Vitter was the only senator who didn’t vote on a Republican-backed budget plan Tuesday night.

“Instead of putting his constituents first, he was seen sipping on a microbrew with New Jersey Governor Chris Christie in Louisiana for his gubernatorial bid,” Dardenne said. ” Louisiana is in desperate need of real leadership and unfortunately it already seem like Senator Vitter is ready to give us more of the same in Louisiana, putting his own personal ambitions ahead of the needs of the people.”

According to the Associated Press, the Senate passed the nonbinding measure by a nearly party-line 51-48 vote, and the House adopted it last week. (Read more about what the legislation means here.)

Dardenne and Vitter, both Republicans, also face Democratic state Rep. John Bel Edwards and Republican Public Service Commissioner Scott Angelle in the Oct. 24 election. If no candidate gets more than 50 percent of the vote, a Nov. 21 runoff will be held between the top two vote-getters.
