A commenter at Balloon Juice writes about wingnuts:
Wingers will never be more or less sane, or more or less stupid. They will always be as bat-shit insane and pig-ignorant as they always have been. The only factor to be considered is our perception of them. It’s not that they get crazier and stupider. It’s that each time they say or do anything, we perceive them as advancing teh crazy/stupid ball one step further. This is not the case; we merely witness one more tentacle of an infinitely insanely stupid entity.
But if the president is just as popular a year from now, this theory could be blown out of the water. I definitely believe that the crazy will reach unprecedented levels if we're heading into the Summer of 2010 with a liberal president in the upper 50s and 60s.
