“MIT economist Jonathan Gruber is one of the foremost architects of Obamacare, having bragged that he “knows more about this law” than anyone else in his field. He’s also emerged as an unintentional one-man wrecking ball against Obamacare, making public statements that have undermined the Obama administration’s legal and political defenses of the president’s signature domestic legacy.
