Where did this race happen?
And oh, I know about "stealth" people, socialist or otherwise. My state LP had to boot out a rabid racist named Martin Lindstedt. Somehow, he managed to get on the last ballot as a REPUBLICAN guv candidate! If I were in the Missouri GOP, I wouldn't have let this guy run.
Northern California, Contra Costa County, I don't know what district it goes by. Ellen Tauscher (waste of skin be she...) ran unopposed by a republican in the last race.
The "Libertarian" candidate actually took ~28%. They could have mopped with a good campaign and a real Libertarian...
