Sounds weird? I thought so too. That thesis has been popping up all over the internet today.
For example, from the Washington Post:
...It’s as if an umpire tweaked the rules to favor his team in the future, but obscured the changes by calling a particular contest for the other side. ”John Roberts is playing at a different game than the rest of us,” wrote Red State’s Erick Erickson. “We’re on poker. He’s on chess.”
By voting with the liberals to uphold the Affordable Care Act, Roberts has put himself above partisan reproach. No one can accuse Roberts of ruling as a movement conservative. He’s made himself bulletproof against insinuations that he’s animated by party allegiances.
