This morning's New York Times begs your pardon for an error in yesterday's editorial that said no winner of a contested caucus had ever gone on to win the White House. Turns out Dubya did, in 2000. We know the Times is rabidly anticipating the end of the Bush administration, but how hard is it to look up what happened the election before last? Admittedly, this whole "caucus" concept is a toughie. Yesterday, two of the most popular searches on Google, according to Room 8 founder Gur Tsabar, were "Iowa caucasus" and "caucasus," neither of which look quite right. A Caucasus isn't so much an agonizing exercise in televised self-government as a Russian mountain range. God Bless America.
