Coburn, Carson in dead heat

The latest poll numbers from Wilson Research in the Oklahoma U.S. Senate race shows conservative Republican Tom Coburn 2 points behind liberal Democrat Brad Carson. It appears that Carson's ad campaign trying to redefine himself as a conservative has had some impact. All the cross-tabs are available in this PDF file.

The overall numbers: Coburn at 37%, Carson at 39%, Bilyeu at 6%, and 19% undecided. Margin of error is +/- 4.4%. From last week, that's a 5% drop for Coburn, a 3% gain for Carson, a 2% gain for Undecided, and a 1% gain for Bilyeu.

Some interesting internals:

• The more educated, the more likely to support Coburn -- Coburn leads 45-36 among those with a post-graduate education, 43-34 among college graduates, 39-37 among those with some college, but trails 28-45 among those with a high school graduation or less.

• Coburn only leads 49-26 among self-described conservatives.

• Coburn only leads 55-24 among Bush supporters, 56-23 among Republicans.

• Coburn leads in four of the five congressional districts -- the exception is CD 2, where he trails 25-58.

• Coburn leads in only one age group -- 25-34, where he leads 55-27.

• Marriage amendment supporters are almost evenly split, favoring Coburn 42-38.

The poll also covers the presidential race (Bush leads 59-29) and five of the state questions.
