Minnesota weather and liberal politics

It's snowing in Minnesota, or at least parts of it. This is not typical, although we denizens of the North Star State certainly pride ourselves on our harsh weather and our ability to tolerate it. We often exaggerate how cold it gets. It makes us feel important, unusual, unique. Certain pundits think that the weather, and our traditionally liberal politics (more or less), are linked.
