Ralph Nader

So apparently Nader is running for the Presidency. I thought it was a bit strange for him to be jumping in this late. I do like the idea of third party candidates bringing new views in instead of keeping the moderate-ness of the Democrat/Republican deal. I don't know that he is exactly the right person to be doing this, but at least someone is. It kind of sucks though, because he is basically just the candidate that is different than the others. And I think he is trying to use that to his advantage. I was on his website, and it says: Which side are you on?- with all of these negative things: Corporate greed, power, control, criminals/Polluters/etc. or Nader's side. And so far, all he is doing is attacking Clinton and Obama. Which is pretty annoying, I wish more politicians could be positive. So... what do you guys think of him/the fact that he is running?
