9 percent of voters have already cast ballots:

Their preference: Barack Obama over John McCain, by 60-39 percent.

That leaves 91 percent yet to vote, but more are coming. A total of 34 percent of likely voters intend to vote early, including those who’ve already done so and those who say they will in the next week. This overall early voting group favors Obama over McCain by 59-39 percent, essentially the same as it is among those who’ve gotten it done already.
