This election has been most difficult for U.S. Senator Mary Landrieu (D-LA) with one mistake after another taking her off message. First it was discovered that she was charging taxpayers for at least four campaign flights. Her embarrassing mistakes were not something Louisiana voters should expect from a Senator with so much experience. Mary Landrieu has been in political office since 1979 and has served in the U.S. Senate since 1997. It is inexcusable for Landrieu not to know that taxpayers should not be charged for campaign air travel.
