AP has picked up the "McCain doesn't know how many homes he owns story"

This is the beginning of a very bad story for John McCain. Days after saying that you're aren't "rich" unless you make over $5 million a year, he acknowledged yesterday that he has no idea how many homes he owns. His campaign now claims he owns 4. Newsweek estimates the number at 7 or so. And Mrs. McCain herself has said "8 or 9." First off, why doesn't McCain know how many homes he has? Is he not remembering things now (again)? Second, who has so many homes that they don't know how many they have? Third, why can't the McCain campaign itself even seem to find out how many homes McCain has - they claim 4, Newsweek says there are far more? I mean, McCain is lucid enough to answer the question, out of the glare of the media lights, isn't he?
