There's much good news for Obama (and precious little for McCain) in today's Quinnipiac swing state analysis.
Update: The Q-polls have been absorbed by Nate Silver and there's a rare early post at 538. Today's projection shows Obama winning about 85% of 10,000 simulation runs, with 51.4% of the popular vote, and carrying the Kerry States + OH, FL, NV, NM and CO, for a total of 336 EVs. Is that what November 4th will look like? Don't believe it for a minute. All elections tighten. This one will do the same--only more so, I predict--and I just can't believe that Obama will carry OH and FL. The 3N vote will be strong in those states.
But right now, Obama doesn't need OH and FL. This is the best Obama has looked on 538 all year (RCP and Electoral-vote.com give similar strong showings on their electoral maps). Going into October, this is definitely his election to lose.
