Landrieu is going for her fourth consecutive term and would really be bucking the odds by achieving another victory. She would be defeating a solid candidate in a very Republican state. According to the DWB index Louisiana was 21.1% pro Republican in 2012 and 25.8% pro Republican in 2008 with Romney and Mccaine winning the states by 17 and 19 percent respectively.
Bill Cassidy leads Mary Landrieu by 3% in the only recent poll taken. Polls taken in late July and late June showed the race even tighter with Cassidy ahead by 1% and .5%.
As of August 2nd, Landrieu has out spent Cassidy by a huge margin so far. 8.5 million to 3 million.
However, Cassidy has a slight advantage when to comes to cash on hand with a 5.6 to 5.5 Million advantage.
