6.4 million people signing up for obamacare this year, an increase of 400,000 new enrollees over the same period a year ago. >> reports of obamacare's deaths have been exaggerated. this is something that withstood two supreme court challenges and presidential elections and a strategy fromç republicans to sabotage it. >> reporter: the five states with the most people signing up during the latest enrollment period were from florida, texas, north carolina, georgia and pennsylvania. ironically, all of them were carried in the election by president-elect trump. mr. trump made it clear what he thinks of the affordable care act. at points calling it flawed, expensive and saddled with triple digit rate hikes in some states. >> if we don't act, the damage will be irreversible. we're going to act. that's why we're going to repeal and replace obamacare. we have no choice.
