In today's UPS delivery I received a nice, very hard hardcover review copy of Hard Call: Great Decisions and the Extraordinary People Who Made Them, by John McCain with Mark Salter. It was evidently going to serve as this campaign's Profiles in Courage (which with typical JFK restraint and class didn't need a subtitle to tell the reader that its author was extraordinary and great). So what's the purpose of the book now, after the hard calls McCain made the other week to pretty much close up shop?
