Louisiana Senate
FILE - In this March 11, 2009 file photo, U.S. Sen. David Vitter, R-La., talks during a news conference discussing the economy on Capitol Hill in Washington. Vitter survived a 2007 prostitution scandal and has shrugged off fresh questions about his judgment in allowing a knife-wielding aide to remain on his staff for more than two years. Vitter has been dogged by questions about his personal life. Yet in a GOP year and in a GOP-leaning state, the incumbent is on track to win the Saturday, Aug. 28, 2010, primary against two little-known Republicans. He has been more focused on Democratic U.S. Rep. Charlie Melancon, his likely opponent in November. (AP Photo/Harry Hamburg, File)
