MLK holiday and history

I just heard McCain speaking today in Memphis and he said that he made a mistake when he voted against the MLK holiday in 1983.

I wonder if this will do anything to stop that particular talking point on the left side of the blogosphere? Probably not. But I wonder if those same people know that John F. Kennedy voted against the 1957 civil rights act when he was Senator?

It's an interesting world, isn't it?
