Et tu, Ron?

As President Obama read former Aetna CEO Ron Williams' op-ed in the Wall Street Journal renouncing his support for a key provision of the health care reform law, he must have felt like Julius Caesar when Caesar realized, as he drew his last breath, that his close friend Brutus was in cahoots with his assassins.

Williams' betrayal appeared in last Monday's edition of the Journal under the headline, "Why I No Longer Support the Health Insurance Mandate." The fact that it was published just days before the Supreme Court was expected to rule on the constitutionality of the mandate made it clear that Williams was not the trusted advisor the President thought he was, that, like Brutus, Williams had thrown his lot with those plotting against the commander-in-chief.
