Yellow Dog Republicans

Once upon a time in South Carolina election day meant Democratic Primary day. There was a popular expression used to describe white southerners back in the days of the "Solid South." They were called (and embraced the term) "yellow dog Democrats." By which it was meant that they would sooner vote for a yellow dog on the Democratic ticket than a Republican. Last night confirmed beyond a shadow of doubt that the pendulum has now swung all the way.
