As the number of undecided voters has dwindled, so has the number that says their minds can still change. More than nine in 10 of each candidate's voters now say they have made up their minds about who to vote for and are not likely to change. Just seven percent of Obama voters and 8 percent of McCain voters say they still might change their minds.
With two days to go, only 8 percent of likely voters are uncommitted – either they have not yet chosen a candidate, or their minds could still change. Nearly all of these uncommitted voters say they plan to vote.
Today's uncommitted voters are mostly white, and more than half are age 45 or older. Just over half are men, and most live in the Midwest and South. Half describe themselves as moderate, and many are not partisan - four in 10 are independents.
This poll was conducted among a random sample of 908 adults nationwide, including 804 registered voters, interviewed by telephone October 30-November 1, 2008. Phone numbers were dialed from RDD samples of both standard land-lines and cell phones. The error due to sampling for results based on the sample of registered voters could be plus or minus four percentage points. The error for subgroups is higher.
