Could our votes for Obama in Arizona actually count?

Obama neck and neck with McCain in Arizona

Sen. John McCain's once-comfortable lead in Arizona has all but evaporated, according to a new poll that has the underdog Republican presidential candidate struggling in his own backyard.
With less than a week until Election Day, McCain is leading his Democratic rival, Illinois Sen. Barack Obama, by 2 points, 46 to 44, down from a 7-point lead a month ago and a double-digit lead this summer, according to a poll from Arizona State University.
Factor in the 3-percentage point margin of error, and a race that was once a nearly sure thing for McCain is now a toss-up, pollsters say.
