How long have AP-Gfk been polling?

Pollster John Zogby: “Three big days for Obama. Anything can happen, but time is running short for McCain. These numbers, if they hold, are blowout numbers. They fit the 1980 model with Reagan's victory over Carter -- but they are happening 12 days before Reagan blasted ahead. If Obama wins like this we can be talking not only victory but realignment: he leads by 27 points among Independents, 27 points among those who have already voted, 16 among newly registered voters, 31 among Hispanics, 93%-2% among African Americans, 16 among women, 27 among those 18-29, 5 among 30-49 year olds, 8 among 50-64s, 4 among those over 65, 25 among Moderates, and 12 among Catholics (which is better than Bill Clinton's 10-point victory among Catholics in 1996). He leads with men by 2 points, and is down among whites by only 6 points, down 2 in armed forces households, 3 among investors, and is tied among NASCAR fans.”
