You've probably seen this story - Wikipedia has been watching edits traceable to House and Senate IP addresses very carefully, even blocking them in some cases, because Congressional staffers have been "vandalizing" pages. You know - removing material unflattering to a Member and replacing it with an official sanitized biography, slandering other members, and so on.

But this fragment really caught my eye:

Someone coming from a Senate IP address edited Senator Coburn's page to add that he was a, "huge douche-bag". Those entries were later removed by Wikipedia.

The House all goes through one proxy server, so all Internet communications from anyone in the House of Representatives looks like it comes through a single IP address. The Senate, however, has individual IP addresses for each office or computer, so it's more traceable.

My question: does the Senate IP address that called Tom Coburn a "huge douche-bag" belong to a Republican or Democratic Senator? The GOP isn't too fond of old Tom, as you know…
