Could well be, and could well happen. If it were to happen the party spin-machine of the candidate he said he favoured would promptly move into action making the same point you have, Wolfgang, and saying that this clearly indicated that Bin Ladin wanted the other man to win.

What would really be needed would be for it to be a secret tape that hadn't been intended for public consumption, but had been obtained at enormous risks by some heroic CIA agent. (Perhaps a doubly heroic agent, who had leaked it to Kerry, if it were such as to help him.)

In which case the spin would be that it was a fake.

And in both cases the spin would probably be true.
