This week was a time of penance. President Obama apologized for having given the impression that insurance policies would not be cancelled due to Obamacare. And 60 Minutes correspondent Lara Logan apologized for a Benghazi report that included an apparently false account by a security contractor. It's a good start; maybe these apologies will open the floodgates. Like maybe Sen. Lindsay Graham can apologize for using the faulty CBS report as an excuse for placing holds on all administration nominees. Or how about an apology from the GOP for the 47 million people affected by painful food stamp cuts that just took effect? Or, wider still, one for all the budget stunts that have cost the economy an estimated $700 billion? And why stop there? How about one for the financial crisis? Or for the mother of all unapologized-for misdeeds, the Iraq War? Wouldn't it be great if accountability were contagious?
