Ralph Nader, as it turns out, is just as bad as your average Washington insider. His self-righteous moralist holier than thou rhetoric doesn't hold up to some of his own actions. Check it out.

Ralph has done a world of good, and yes, the two corporate parties do have a stranglehold on the election, and yes, he and anyone else that wants to run should be able to, but damn Ralph, don't you see how important this one is?

The root site of the above link has dirt on pretty much every candidate since 96, with a few very thin dirt, including John Kerry surprisingly. Check it out. It's a rather non-partisan site with some muck on candidates from all sides of the political spectrum.
