The exit polls suggest that race was a factor in a lot of voters' decisions — and that, on balance, it worked to Barack Obama's advantage. In Ohio, for example, six percent of voters said that race was the most important factor in their decision. Among them, Obama won 59-40. Another 13 percent said race was an important factor in their vote, and Obama won among them, 52-46. So nearly one in five voters said race was an important part of their decision, and more of them voted for Obama than McCain.
Beyond that, eight percent said race was a "minor factor" in their decision — and they went for McCain, 56-44. Finally, 71 percent said race played no role at all in their decision — and Obama won among them, 54-45.
