WASHINGTON (AP) — It seems to be something of an occupational hazard for President Barack Obama: When he talks about his health care law, he’s bound to hit a fact bump sooner or later.

So it went Tuesday night, when he declared Medicare premiums have stayed flat thanks to the law, when they’ve gone up. As for an even bigger theme of his State of the Union address, the president’s assertion that “upward mobility has stalled” in America runs contrary to recent research, while other findings support him.
