Tim Bee seriously explored running for the AZ-08 open seat and is term limited out of his current office in 2008. The best explanation in my view for why he did not run is because he considered it too risky compared to the alternative (an excellent shot at AZ Senate President).
Just flagging with this poll because I can't think of a better thread and I don't want to post a new one.

Siena College releases a poll today on NY-20 showing Sweeney ahead of Gillibrand by a 53-34 margin.
Although it's a uni congressional poll in the middle of the summer, it's at least an Indy poll. That entitles it to something, though I don't know what exactly. :)
