Check out what Zogby actually said about his latest round of polls.
"McCain is well within striking distance in each of the six states in which he trails. None of Obama's leads are outside the margin of error. However, unless McCain can take one of the big states won by John Kerry in 2004, such as Pennsylvania, he needs to win these six states. He might be able to survive the loss of Nevada, but probably not any of the others."
I actually had a lot of fun over at 270towin.com trying to find ways for McCain to win the Presidency while losing one of those states. The closest I could come to something plausible was McCain somehow flipping Pennsylvania, where he is currently behind by double digits in every public poll, or Michigan, which would involve the old sitcom "Candidate Pulls Out of Race, Propelling Him to Victory!" twist.
So, um, yeah. Not over yet, but don't believe anyone who tells you the Zogby poll looks like good news for McCain.
