Paul Krugman: Obamacare will work
"But this confrontation did start with a real issue: Republican efforts to stop Obamacare from going into effect. It’s long been clear that the great fear of the Republican Party was not that health reform would fail, but that it would succeed. And developments since Tuesday, when the exchanges on which individuals will buy health insurance opened for business, strongly suggest that their worst fears will indeed be realized: This thing is going to work."
