Why Does Claire McCaskill Suck So Much? (4)

Amusingly for me, McCaskill merits ridicule in Kos's quick hits from today:

I'm so relieved that we have Sens. Claire McCaskill and Ben Nelson in our party protecting us from the tyranny of building and renovating schools. Oh, and life-saving medical care.

And remember, McCain won Nebraska by 15 points. Nelson's excuse to being a douche bag is that his state is horribly Republican. What's Claire's?
