Roll Call reported this afternoon that Rep. Rick Renzi, R-Ariz., has decided not to seek re-election, "ending months of speculation regarding the ethically clouded congressman's political future."
"Renzi's retirement announcement adds to a list of GOP Members planning to depart upon the conclusion of the 110th Congress, including Reps. Ray LaHood (Ill.), Deborah Pryce (Ohio) and Chip Pickering (Miss.), as well as former Speaker and Rep. Dennis Hastert (Ill.)."
"But while some of those retirements and the open seats they are creating could cause problems for the Republicans' hopes of recapturing the majority, Renzi's departure could help the GOP by allowing them to nominate a replacement that is free of the ethical baggage that appears to have ultimately undone the Congressman's future."
Despite that, Democratic Congressional Campaign Committee spokeswoman Jennifer Crider issued this statement: "Rick Renzi is following the Republican Conference corruption playbook -- both Bob Ney and Duke Cunningham announced they were 'retiring' before they pleaded guilty and resigned. The people of Arizona's First Congressional District deserve to be represented by someone who puts them first and is free of criminal and ethical scandal."
