According to Chris Matthews, the fact that racists have during the history of the nation invoked the rights of the states to perpetuate slavery or segregation immediately renders all proponents of states' rights -- a pillar of federalism and the American Constitution -- racist.

While Matthews and his Hardball guests on Tuesday cited names like Jim Crow and John Calhoun and compared them to Texas Gov. Rick Perry and Deborah Medina, Perry's libertarian-leaning opponent in the upcoming GOP primary, the names of the nation's founders -- who were ardent advocates of states' rights -- were conspicuously absent.

Matthews claimed to give his viewers a lesson in the meanings of "interposition" and "nullification" as they relate to the rights of the states and the Constitution. But he didn't say what they meant.

He just read a quote from Martin Luther King Jr. mentioning those terms as they related to the civil rights movement (video below the fold - h/t Liz Blaine of NewsReal).
