I heard an idea floating around NPR today, that Nader being so much further left than Kerry, it will paint Kerry to be a more moderate candidate by pushing the debate further left. Kerry will be in a better position to pick up any swing voters if he come off as the more moderate of the three candidates. Its just an idea. I don't know how much water it holds. It sounds like a more hopeful perspective for those on the left, but it may not be the most realistic perspective.
Personally I feel pushed further and further away from the left and the right. This election year is already ugly, and is not going to get any prettier anytime soon. My vote usually goes to the right, but I'm not sure anymore, Bush is driving me crazy with dropping cash on anything that comes his way. I'm glad there is plenty of time until the election to make up my mind, but I fear that the centrists in this country will be more an more alienated as the election grows nearer. The political dialogue in this country seems to taste worse and worse every year. No matter what, I can't stop drinking the stuff though.
