When the US Supreme Court finally gave the Affordable Care Act the go-ahead last year, President Obama called it a victory. "In America, healthcare is not a privilege for a few, but a right for all." But there's still one system for the affluent and another for everyone else -- even though millions who were not insured can now buy policies. More and more often, doctors and hospitals tell them, "We don't take Obamacare here." Now, some insurance companies are opting out of the program. Healthcare's a major issue in yet another presidential campaign.
