The Rasmussen Reports daily Presidential Tracking Poll for Sunday shows the race tied with President Obama and Mitt Romney each attracting support from 49% of voters nationwide. One percent (1%) prefers some other candidate, and another one percent (1%) remains undecided.

These figures include both those who have already voted and those likely to vote. Obama leads among those who have already voted, while Romney leads among those deemed likely to vote. Thirty-nine percent (39%) of voters are projected to be Democrats and 37% Republicans. Both candidates do well within their own party, while Romney has a nine-point advantage among unaffiliated voters.

One key to the outcome on Election Day will be the racial and ethnic mix of the electorate. In 2008, approximately 74% of voters were white. The Obama campaign has argued that this will fall a couple of percentage points in 2012 with an increase in minority voting. Others have noted the increased enthusiasm among white voters and the decreased enthusiasm among Hispanic voters and suggest that white voters might make up a slightly larger share of the electorate this time around. It is significant because Romney attracts 58% of the white vote, while Obama has a huge lead among non-white voters.

If the white turnout increases on Election Day, it will be very difficult for the president to win. If it decreases, it will be very difficult for him to lose. Rasmussen Reports currently estimates that white turnout will be similar to the 2008 totals. Black voters, however, are far more likely to have voted already than any other segment of the electorate.
