The left wants to define the “far right” to use as a means of driving wedges. The evolution question asked of Jeff Sessions is a good example of what they’re trying to do. They want to divide creationist conservatives from evolutionist conservatives. Personally I think this left wing fantasy can be used against them.
The people who actually do fit the KKK mold are more left than right these days as it is. David Duke has had a webpage dedicated to support for Cindy Sheehan for several years now and the KKK has had anti war rallies.
