John Shadegg will announce his retirement from Congress today. Senator Jim Waring is a likely candidate, as is Shadegg staffer Sean Noble, who nearly moved to CD 5 to challenge Harry Mitchell. Waring has a record of sponsoring popular bills, from a variety of measures to combat drunk driving to banning taxpayer financed political advertising. He’s also a notoriously hard worker, who meets thousands of his constituents at their doors every year, and as of the latest rounds of filings leads the State Senate in fundraising. Noble will have to work harder to introduce himself to the public, making the difficult transition from staffer to candidate, but he’s a skilled political operative and it’s likely Shadegg will work hard to help him succeed. For now, I’d give the edge to Waring.

Tom Horne and Dean Martin have been mentioned as candidates in the event Shadegg were to retire, but his surprise 2008 retirement would force either to give up a statewide office for the mere chance to run.

Who else could get in this race? What is everyone else thinking?
