The Washington Post notes some of the mud that flew during a local Republican primary. Check out the jab they take at Gun Owners of America.(emphasis mine)

In the bitter Republican primary, Frederick pounced on Rollison's endorsement of last year's failed referendum proposed on the sales tax, nicknaming him "Sales Tax Jack." The challenger appealed to Prince William conservatives by pledging to back school vouchers and capturing an endorsement from the Springfield-based Gun Owners of America, a group many consider more extreme than the National Rifle Association.

I find it interesting that people that advocate freedom and less government intervention in their lives are considered extreme.
