SEN-LA: Landrieu Ahead But Catch

CNN/ORC International is out with a new poll in Louisiana finds Senator Mary Landrieu (D) just slightly ahead over challenger Bill Cassidy (R) in the U.S Senate race, 43% to 40%. But in Louisiana you need a majority of the vote in order to win the election, so unless Landrieu or Cassidy can win with 50% of the vote then it will trigger a December run-off against the top two candidates with the most vote, Landrieu and Cassidy.

So potentially, we could have to wait until December to find out who controls the U.S Senate.
