Judging from his Wikipedia article, Stapleton sounds like quite the rising star (and Edmunds quite the kook). I do hope he wins, or at least pushes Schweitzer's margin of victory into the low single digits.
I've crawled his Facebook page, and you should be a little concerned with the fact that he's said the sequester doesn't cut far enough. But other than that and throwing around comparisons to the Soviet Union when Montanans want to expand welfare, haven't seen much.
Ironically the USSR was far less tolerant of welfare than the US.
