In order for the GOP to net 6 seats that would have to include winning both runoffs in LA and GA. Landrieu is no stranger to runoffs either. She handily def Tyrell at the height of Dubya's popularity. And Cassidy just stuck his foot in mouth about another Romney 47 percent comment. But winning AK and NC is ideal and not depend on a runoff for control, but if we have to, we have a chance to win either Ga or La.
Although Landrieu is indeed experienced in winning runoffs, I think that the state of Louisiana has drifted in a more conservative direction since her last victory in 2008, negating her experience with winning close elections.
Louisiana was one of only six states Obama did better in 2012 than in 2008
