David Vitter:

Cowardly chickenshit.  I understand that Republicans need all the votes they can get in the Senate, really I do.  After all, Democrats have to hold their noses while the likes of Joe Lieberman stab them in the back.  But I cannot for the life of me fathom how any Republican with a shred of conscience can support a hypocritical, venal, racist, perverted waste of oxygen like Vitter is beyond my ability to comprehend.
