Sen. Barack Obama holds a sizable advantage over John McCain just two days before the longest and most expensive presidential campaign in history comes to a close.
After nearly two years of ads, rallies, debates and barnstorming, Obama is up 54 to 43 percent among likely voters, in the new Washington Post-ABC News tracking poll. And the ranks of persuadable voters has dwindled to 7 percent heading into the final day. One part of McCain's steep challenge is that more than a quarter of the probable electorate has already voted - among these early birds, 59 percent said they voted for Obama, 40 percent for McCain. http://voices.washingtonpost.com/behind-the-numbers/2008/11/wapo-abc_tracking_advantage_ob.html?hpid=topnews
