The Republicans who consider themselves possible contenders for their party's 2012 presidential nomination may have their eyes fixed on the political horizon. But they probably should be watching their backs, too.

This was brought to mind by comments that Louisiana Democratic Sen. Mary L. Landrieu made on national TV about Bobby Jindal -- her home state's governor -- who, at age 38, is widely regarded as one of the Republican Party's rising stars and a possible 2012 prospect.

Landrieu, appearing on C-SPAN's "American Morning", said, "Well, if he would stay home in Louisiana a little more and focus on being governor that would be wonderful."
