In an otherwise uplifting piece in the Christian Science Monitor about the Montana tradition of volunteering for the armed services, the author offers the following explanation (which doesn’t match up with the “long-standing tradition” thesis in the rest of the story):

Montana has few FM radio stations. So young people hear mostly AM radio, where they find the “airwaves dominated by prowar defenders of the Bush administration.”

Yep. They’re a bunch of ignorant hicks in Montana who can’t read a newspaper and have never heard of the Internet. That’s why they are foolish enough to enlist.
