Next Dem target for primary challenge

I know that lots of lefties were very happy that Ned Lamont challenged and then won the Democratic primary against Joe Lieberman, and that kos has proposed havinig more intra-party challengers. I nominate another Joe - Joe Biden for the next primary challenge (it's sorta like American's Next Top Model, but for greying, balding white male political egoists.)

He has a propensity for saying plenty of stupid stuff on camera like his "You can't avoid Indians accents in Dunkin Donuts" bit to an Indian American admirer (caught on youtube.)

Now he touts his racist credentials to a Southern audience:

Delaware, he noted, was a “slave state that fought beside the North. That’s only because we couldn’t figure out how to get to the South. There were a couple of states in the way.”

So the man wants to make a run for president in 2008. Coincidentally, his Senate seat is up in 2008. Let's see if we can't make him lose both. As Wonkette says, "even his very own Macaca moment was lame." Well, okay - we won't have to lift a finger to watch him lose the presidential primaries. But we'll have fun laughing.
