In the month prior to the Iowa caucuses, SurveyUSA questioned registered voters in 15 states about whom they would vote for in a head-to-head matchup between Obama and Huckabee. Obama carried 10 states to Huckabee's 5.

Not surprisingly, Obama carried Massachusetts, California, New York, Oregon and Washington by relatively large margins. But he also took Virginia--which hasn't voted for a Democrat in a Presidential election since 1964--by 9 points. He carried swing states Iowa and Wisconsin--each decided by just 1 point in 2004--by double figures, and Minnesota by 5 points. He technically took Ohio, but the margin was just 1 point.

All of the states Huckabee won were carried by President Bush in 2004. His weakest margins of victory were in the Southwest and Midwest states of New Mexico and Missouri. He also carried Kansas, Kentucky and Alabama.
