Just as Coastal Democrats differ from Interior Democrats, Republicans come in regional varieties.
Or so argues Jacob Weisberg in Slate, an online magazine owned by the Washington Post. He sees three GOP regions: Northeastern, Southern and Western.
The Northeastern -- the moderate variety -- is nearly extinct, though showed signs of life with Scott Brown's victory in the Massachusetts special election for a U.S. Senate seat.
Both the Western and the Southern are big on guns, Weisberg writes. But the Southern GOP is culturally conservative and rather religious. Out here, Republicans tend to be more libertarian, less focused on cultural matters and more concerned with opposing big government.
And many of the comments are as interesting as the essay.
