In 1979, the black-footed ferret was declared extinct. Then a woman named Lucille Hogg discovered a handful of the little critters — popularly known as prairie dog hunters, on account of their primary food source — sitting on her doorstep, carried from goodness knows where by her dog. Since then they have been bred successfully both in captivity and in the wild, most notably in South Dakota, where they nevertheless remain a federally designated endangered species. Democrats in the Mount Rushmore State are faring somewhat worse than America's only indigenous species of ferret. Democrats have not held the governor's mansion since 1979, and no Democrat has ever served as governor for more than two terms in the 129-year history of the state.
