If the Supreme Court strikes down President Barack Obama’s signature health care reform law, 77 percent of Americans want the president and Congress to work on new legislation overhauling the system, according to a new AP-GfK poll on Wednesday. Only 19 percent of Americans want lawmakers to leave health care the way it is. The AP poll shows opinion on Obama’s handling of health care law to be remarkably consistent: 48 percent of Americans approve of the way Obama is handling the issue and 50 percent disapprove.
