For four of the past five years, PolitiFact’s Lie of the Year has revolved around the health care law, which has been subject to more erroneous attacks than any other piece of legislation PolitiFact has fact-checked.

Obama’s ideas on health care were first offered as general outlines then grew into specific legislation over the course of his presidency. Yet Obama never adjusted his rhetoric to give people a more accurate sense of the law’s real-world repercussions, even as fact-checkers flagged his statements as exaggerated at best.

Instead, he fought back against inaccurate attacks with his own oversimplifications, which he repeated even as it became clear his promise was too sweeping.

The debate about the health care law rages on, but friends and foes of Obamacare have found one slice of common ground: The president’s “you can keep it” claim has been a real hit to his credibility.
