Romney currently leads Obama 52% to 45% among voters who say they have
already cast their ballots. However, that is comparable to Romney's 51% to 46% lead among all likely voters
in Gallup's Oct. 22-28 tracking polling. At the same time, the race is
tied at 49% among those who have not yet voted but still intend to vote
early, suggesting these voters could cause the race to tighten.
Romney leads 51% to 45% among the much larger group of voters who plan
to vote on Election Day, Nov. 6.
