re: If Cassidy ends up ahead of Mary, she should just concede

I do not see a plausible scenario in which Landrieu wins the runoff. If at the end of the evening majority control of the Senate had still been up in the air, then she knew that there would be tons of money invested in the Louisiana race. With national attention directed toward Louisiana, she might have been able to generate some enthusiasm among her base voters. It would have still been a bit of a long shot, but it would have been possible.

Now that GOP control of the Senate is confirmed, there is going to be a major drop-off in the intensity of this race. What is she going to say to motivate her voters? "Vote for me--let's reduce the Republican majority from 54 to 53 seats!!" Is that the rallying cry that would get her elected?

Bottom line: Landrieu is toast.
