Here's part of what Mike Rogers wrote about outing another Rep Senator:

He narrows it down to 33 (he's doing the tease/ intimidation factor)

I notice he says that he's going to reveal it when it's going to be most damaging to that person's reelection effort, so it must be right before that person's election. Elsewhere he suggests that it's coming soon, so I'm guessing it must be a Senator who is up for reelection this November. That eliminates several more senators from the list.
The guy who runs that blog is a bastard, IMO.
On reflection, none of those on that list are up for reelectionthis November , so by revealing it soon he must mean 08. Sheesh, nevermind!
