On April 3, Rep. Bill Cassidy announced his run against Sen. Mary Landrieu, who faces re-election in 2014. One Republican candidate and two Democrats have since entered the race for Cassidy’s open seat.

Republican Paul Dietzel is the first candidate so far to sign the Taxpayer Protection Pledge, but others could join him as they jump into the race. Politics1 lists Dan Claitor, Hunter Greene, Erich Ponti, and Chas Roemer as potential challengers.

The Cook Political Report rates the race as “Solid Republican” with a Partisan Voter Index of “R+21.” In the 2012 presidential election, Mitt Romney carried the district with 66 percent of the vote.

Due to Louisiana’s “jungle primary” system, the first ballots will be cast on November 4, 2014. Unless a candidate obtains a majority, a runoff contest will be held for the top two vote-getters on December 6. When it comes time to vote, the people of Louisiana’s 6th District will know which candidates are committed to protecting them from higher taxes.
