Is the election already decided? Nate Silver flags some important data from Colorado and New Mexico. According to new polls, two-thirds of Coloradans have already cast their ballot and Obama has a 10-point lead; 55 to 60 percent of New Mexicans have also already voted, with Obama leading there by 17 points. Elsewhere, Nevadans have already reached 53 percent of their 2004 voting totals, and Obama has a 23-point lead in Las Vegas’ Clark County and a 15-point lead in traditionally Republican Washoe County. These states plus Virginia and Iowa spell an Obama victory, even if McCain’s Hail Mary succeeds in Pennsylvania.
