“If, somehow, the private market doesn’t respond the way that it’s supposed to [to other aspects of health care reform], then it would trigger a public option or a government-run option,” Nebraska Sen. Ben Nelson said Sunday on CNN’s State of the Union, “but only as a fail safe, backstop to the process. And when I say trigger … I don’t mean a hair trigger. I mean a true trigger – one that would only apply if there isn’t the kind of competition in the business that we believe there would be.”
