BATON ROUGE, La. (AP) - Republican U.S. Rep. Bill Cassidy has made it official: He's a candidate for the U.S. Senate race next year.
He's hoping to oust third-term Democratic U.S. Sen. Mary Landrieu from her seat.
Cassidy kicked off his campaign Wednesday with a video announcing his candidacy and with campaign stops planned in Jefferson and St. Tammany parishes.
Cassidy, a Baton Rouge doctor elected to Congress in 2008, is the first Republican to declare his intention to run for the Senate seat - though other GOP contenders are considering getting into the race.
In his announcement video, Cassidy shows what is likely to be a regular campaign strategy. He repeatedly ties Landrieu to President Barack Obama, who remains unpopular in Louisiana and who Cassidy says is out of step with the state.
