George Allen dumbness confirmed, limits of dumbness seemingly bottomless

So, I was feeling kind of bad about calling Senator George Allen an idiot. In hindsight, I started thinking that maybe it was a little too disrespectful, maybe a little too coarse, to talk about a sitting U.S. senator like that, no matter the regard I held him in.
Then I saw this totally awesome video of repeatedly calling an Indian kid "Macaca."
Now, let there be no doubt. Dude is a freaking idiot.
How else to explain the senator looking a camera in the eye and repeatedly calling this (Fairfax born) 20 year old UVa student named Sidarth "Macaca" and welcoming him to America, all to the delight of the rednecks he'd assembled in deep, deep Southwest Virginia.
The video is widely available on the internets, you should look it up.
While this incident highlights G. Felix Allen's well-documented disdain for anyone even slightly ethnic, it offends me on a much more personal level.
As my Indian friends can attest, I've been calling them "Macaca" for years, always to hilarious effect. George Allen stole my bit.
