Lindsey Graham's recent warning that Republicans might yet push for a presidential impeachment serves to demonstrate, if further demonstration was still required, just how brutal Washington politics could get if his party ends up in control of both Houses of Congress after the mid-term elections in November.
In the case of the Affordable Care Act, private insurers have priced their policies on the premise that a lot of healthy young people will purchase insurance. If the young don't participate in large numbers, and older and sicker people do, then insurers will have to raise premium charges for everyone. That will be blamed, rightly or wrongly, on Obamacare. We know from the administration that more than two million people have become newly insured. That's good news. But we don't know who they are. Is the Affordable Care Act succumbing to the dread dynamics of adverse selection? The early signs are far from conclusive, but they are not encouraging.
