What he did was make it perfectly clear he will bend over backwards to avoid finding any federal legislation unconstitutional, no matter how insidious the law is.
He is going to be around another 20 years and has telegraphed that the feds can stomp all over our rights without objection from him.
If Congress passed a bill making obama president for life, Roberts would refuse to rule against it.
