Gov. Haley Barbour, with a home state advantage in Mississippi, also topped PPP's survey of the GOP primary field at 37%, followed by Mike Huckabee at 19%, and Sarah Palin and Newt Gingrich at 10%.
The poll also found that voters who thought interracial marriage should be banned liked Barbour, Palin, and Huckabee the most among the slate of potential GOP presidential candidates. Seventy-nine percent of those voters said they approved of Gov. Barbour's job performance, while 74% said they had a favorable opinion of Sarah Palin, and 73% viewed Huckabee favorably.
In February, a Gallup poll found that Mississippi was the most conservative state in the nation. In that survey, 50.0% of adults identified themselves as conservatives.
