Incidentally, my limited anecdotal experience in discussing this issue suggests that a shocking number of people -- including, say, your average radio talk show host -- continues to have major difficulty distinguishing between Medicare and Medicaid. This has always struck me as a nice ancillary boon to Medicaid's defenders, ensuring that a means-tested entitlement program for poor people can enjoy some spill-off support from one of the durable, universal middle-class entitlements.
