Tom Maguire thinks the NSA surveillance leak was supposed to be an October surprise and that Richard Clarke and Rand Beers are likely suspects:

...following the possibility that the story was politically motivated, let's ask about sources, described here as:

"Nearly a dozen current and former officials, who were granted anonymity because of the classified nature of the program".

Both Richard Clarke and Rand Beers were former Administration officials by the fall of 2004, both were involved with the Kerry campaign, and either or both both may have been in the loop when this eavesdropping program was begun in the fall of 2001.

I think he's right.
