Polling Tells Which Story Exactly?

Since we discussed polling, I just saw these two articles in rapid succession and couldn't help but laugh. It just goes to show that one can feel pretty optimistic or pretty poor depending on whom you read and trust. A McCain backer can read the AP report and feel like a million bucks. An Obama would be changing the underwear. Yet, if you're a Washington Post nut, Obama backers can rejoice, while McCain should change the Depends.
