Matthew Miller complains that Gov. Christie has called for trimming Medicare and Social Security but not for raising taxes. “Courage is when a politician tells his strongest supporters things they don’t want to hear. I’m a little tired of Republicans calling for an ‘adult conversation’ that mainly takes things away from adults who don’t vote Republican.” Is Miller under the impression that Republicans don’t collect Social Security? Given the way older voters have trended lately, I doubt that even that “mainly” saves his claim.
