John McCain has repeatedly argued that his wife's financial holdings are separate from his political life, and should remains so for the privacy of her and her children. However, as Slate pointed out this weekend, McCain has no problems keeping nearly everything the couple does own in her name:
Aside from a Wachovia checking account, in which he keeps between $15,000 and $50,000 (wouldn't some of that money earn more interest in a certificate of deposit?), all of the couple's assets are in Cindy's name. John McCain's tax return is so anemic, so marginal to the couple's actual financial situation, that he doesn't even take a deduction for interest on his home mortgage. Presumably Cindy does, since disclosure forms indicate that she has several mortgages.
Presumably, of course, because we can't know for sure. Because John McCain refuses to disclose the information.
