All this talk about McCain's houses gives me an excuse to plug Noam's great story about Cindy McCain, which includes this detail (along with many, many more):
The following January, John Rhodes, the iconic Phoenix representative, decided to retire. The looming primary would determine his successor in such a heavily Republican district, and it attracted two veteran pols in a matter of weeks. But it was McCain who arguably moved the quickest. Within minutes of the announcement, Cindy had found a modest two-story house in a subdivision called The Lakes. The house was in Tempe, just east of Phoenix, and officially made McCain a resident of Rhodes's district.
Anyway, read Noam's piece, and you'll realize Cindy did a lot more than just give McCain the money to own more houses than he can keep track of.
