Now this is odd. Gov. Bobby Jindal (R-LA) has again ruled out running for Senate in 2010, which would involve challenging scandal-plagued GOP Sen. David Vitter in the primary -- but he's not giving any enthusiastic endorsements of Vitter, either.

"Well a couple of things, first (Sen. David) Vitter's going to have to make his case with the voters, just like every candidate does," Jindal said, when asked by a reporter about a possible candidacy. "There's been a lot of speculation. Let me answer your question very directly, I'm not running for the senate, I'm running for re-election as governor in 2011, but David's going have to make his case with the voters directly just like any other candidate's going to have to do that."

Now that's a strong vote of confidence.
