Pennsylvania will not set up its own health care exchange under the federal Affordable Care Act — at least not for now, Gov. Tom Corbett said Wednesday. Setting up a state-based exchange would be irresponsible, Corbett said as he faulted federal authorities for what he said were inadequate answers to his questions about cost and other issues. "Health care reform is too important to be achieved through haphazard planning," said the Republican governor. "Pennsylvania taxpayers and businesses deserve more. They deserve informed decision making and a strong plan that responsibly uses taxpayer dollars."
