Something to chew on from MSNBC’s First Read:
According to [a new NBC/WSJ/MySpace poll], new and lapsed voters (those who didn’t vote in 2004) back Obama over McCain by a 2-to-1 margin, 61%-30%. If you take the Bush (62 million) and Kerry (59 million) vote totals from 2004, assume turnout increases by 20 million additional voters (about what it did in 2004), and assume Obama wins these additional voters 2-to-1, then Obama would best McCain nationally by more than three million voters, 72.4 million to 68.7 million. But if turnout increases by just 10 million, then the numbers become Obama 65.7 million, McCain 65.3 million — a virtual tie. “An Obama victory could very well depend on getting these folks to the polls,” says NBC/WSJ co-pollster Neil Newhouse (R).
Update: Another quirk from new polls, which all show Obama trending up: Obama is opening up a huge lead among women.
Among the [new TIME poll’s] most dramatic findings: McCain is losing female voters faster than Sarah Palin attracted them after the Republican convention. Obama leads McCain by 17 points with women, 55%-38%. Before the conventions, women preferred Obama by a margin of 10 points, 49%-39%. After McCain picked Palin as his running mate, the gap narrowed to a virtual tie, with Obama holding a one point margin, 48%-47%.
