Gov. Bobby Jindal's political adviser offered a terse response Thursday to resurging buzz about Jindal jumping into the U.S. Senate race.

"No interest. At all." Curt Anderson told National Journal. He is partner in OnMessage Inc., the political strategists Jindal uses, and co-author of Jindal's autobiography.

The talk, which is growing louder and louder, is not new.

Speculation has ebbed and flowed for years about Jindal possibly opposing U.S. Sen. Mary Landrieu in 2014.

The governor's term ends in 2016 and he cannot run for a consecutive third term. Chances of him running for the White House seem to have dimmed amid sinking approval ratings in Louisiana.

His entry into the U.S. Senate race would reflect a lack of party confidence in U.S. Rep. Bill Cassidy. Cassidy, R-La., already declared his intent to try to unseat Landrieu, D-La.
