Democratic presidential nominee Barack Obama is entering the third and final presidential debate Wednesday with a wide lead over Republican rival John McCain nationally, a new CBS News/New York Times poll shows.
The Obama-Biden ticket now leads the McCain-Palin ticket 53 percent to 39 percent among likely voters, a 14-point margin. One week ago, prior to the Town Hall debate that uncommitted voters saw as a win for Obama, that margin was just three points.
