If Ohio is still in play, then I’m one of those who looks at the RCP electoral map and thinks, not “McCain’s path to 270 … is narrowing,” but “jeez, Obama could still easily lose,” even if the polls showing his non-trivial national lead are right. He’s got to win one of seven decidedly iffy states (Florida, North Carolina, Virginia, Ohio, Indiana, Colorado, Missouri). You want to rely on Colorado?
The race could still go either way, and may well turn on things that aren’t even in the news at the moment.
