Don’t tread on my health-care law! That’s what President Obama told the Supreme Court Monday, saying that he was “confident” that Obamacare would not be struck down. At a press conference with the leaders of Mexico and Canada, the president reminded the justices that they are an “unelected group of people,” and said he could not see them taking the “extraordinary step of overturning a law that was passed by a strong majority of a democratically elected Congress.” The court heard three days of oral argument on the Affordable Care Act last week.
