Rush Limbaugh railed against the Supreme Court on Thursday after it upheld the individual mandate clause within the Affordable Care Act.

Limbaugh, who threatened in 2010 to move to Costa Rica if universal health care ever passed in the United States (side note: he's still here, and Costa Rica has universal health care), said that Chief Justice John Roberts had "kicked into activist mode" and was interested in building his own legacy.

The controlling opinion, written by Roberts, upheld the individual mandate clause as a tax. In a somewhat unexpected move, Roberts voted against his fellow conservative judges on the Supreme Court.

Limbaugh charged that Supreme Court just deceived the American public "in ways nobody contemplated." He called the ruling "the biggest tax increase in the history of the world," and said that the American people were now "governed by a monstrous assault on [their] personal liberty and freedom."

Limbaugh added that it was now time to "wrap this monstrosity around Obama's head."
