March 23 marks the 6th anniversary of the Affordable Care Act. In the six years since a Democratic Congress enacted the Affordable Care Act, important progress has been made to bring more access to quality, affordable health care. Today, 20 million more Americans have insurance because of the ACA, bringing our uninsured rate to an all-time low. Since the ACA was enacted, health care prices have been rising at the slowest rate in five decades. And with new protections and benefits, everyone's insurance provides preventive services at no extra cost, can't cap coverage, and isn't allowed to discriminate based on pre-existing conditions.
