This looks like a big-time "gotcha" story. When you're poor, it can be hard to pay the bills. When you're rich, it's hard to keep track of all the bills that need paying. It's a lesson Cindy McCain learned the......

I think that's a fair summary, but there are a couple of other angles worth taking into account, just from the perspective of framing and political impact.

It doesn't help that McCain is the guy who said this: "The issue of economics is not something I've understood as well as I should."

If he can't manage his own economic affairs in an efficient and proper manner, that doesn't bode well for his ability to manage the nation's. His statement, and this incident, create the impression that he will delegate economic affairs to unsupervised underlings who will drop the ball. After Bush's track record of fiscal mismanagement and overall ineptness, this is somewhat toxic.

Also, he's old. Old people forget to take care of basic things, like paying bills.

I'm not saying the story is huge. I'm just saying that it highlights some of his existing weaknesses.

"It appears to be a case of misdirected mail."

That's a lame, defensive, childish excuse. If McCain is smart, he won't use it. But I'm not sure he's smart.
