MSNBC’s Chris Hayes, who seems like a nice person, got caught making a huge historical mistake; he said George Wallace, the Alabama Governor who defied a desegregation order 50 years ago, was a Republican. Nope. He was a Democrat and ran in the Democratic presidential primaries in 1964, 1972 and 1976; he also ran for president as a third party candidate in 1968. Hayes either didn’t know that–surprisingly for a political commentator–or temporarily and perhaps conveniently forgot it. Or maybe he just figures that all political villains are Republicans. In any case he apologized for what he, appropriately, called a “stupid, inexcusable, historically illiterate mistake.”

Here’s another fact he and others may want to keep in mind as we remember the climactic events of the civil rights movement 50 years ago: Bull Connor, the Birmingham police commissioner who turned fire hoses and police dogs on peaceful civil rights demonstrators, was a Democrat too. In fact, he was Democratic National Committeeman from Alabama, at a time when each state and territory had just one male and one female member on the Democratic National Committee.
