Mike Huckabee is not a conservative and that won't wash in the South
The conventional wisdom is that Mike Huckabee will carry the Evangelical vote in the south. The only problem is that there is no "Evangelical vote." Most people can't even define the word "Evangelical". Evangelical has become a convenient term used by the media but there is no monolithic group of Evangelicals. There are stark contrasts ideologically, theologically and politically between Christian conservatives and their liberal brethren such as Jimmy Carter.
Do not confuse southern Christians with the more liberal "Evangelical" denominations in other parts of the country. New Anglican churches are springing up everywhere as southern Episcopalians split with New England Episcopalians. Midwestern Lutherans and Protestants are far more liberal than their southern counterparts. Even within the liberal churches there is an on-going struggle over issues such as boycotting Israel.
While polls show Huckabee leading in South Carolina and Georgia, the campaign has hardly begun and people are just now becoming aware of Huckabee's record. In the South Carolina debate this week, Fred Thompson pointed out that Mr. Huckabee is not a conservative. South Carolina Christians heard and loved Thompson's call to the Reagan ideals. Christians across the south will respond the same way and the polls will change. I am not making predictions but I wouldn't be surprised if Huckabee fails to win a single southern state.
