Bush-Cheney New England campaign chair Jim Tobin resigns over election tampering scandal.

A few suggested questions for national political reporters needing to do catch-up on this story.

Tobin was named by the two men who've pled guilty in the case as part of their plea agreements. The Bush campaign has known for months of Tobin's involvement in this case. The only reason he resigned today is that this information was finally pried free from court documents. Why did they keep him in such a senior post if they knew of his role in such serious wrongdoing?

At the time the incident happened Tobin was the Northeast political director for the National Republican Senatorial Committee. This was under Sen. Bill Frist's tenure as chairman. Did anyone else at the NRSC know about this at the time?
