I got tired of John McCain’s phony “maverick” act a long time ago, and his hypocritical performance on the Senate floor this week reminded me why. McCain is a veritable Potemkin village, a conventional Republican pol masking as a truth-telling, straight-talking rebel. Having risen from his sickbed, where he was enjoying Cadillac government health care, he flew across the country to deliver a floor speech lamenting the Senate’s toxic partisanship - scant minutes after he cast a pivotal vote to open the GOP’s toxic partisan quest to strip 20 million people of their health care.
