CQ Politics has changed its rating of the race between scandal-plagued GOP Rep. Don Sherwood and Dem challenger Chris Carney from "No Clear Favorite" to "Leans Democratic." The shift shows once again how Sherwood's recent extramarital affair with a younger woman -- which Carney has not hesitated to make a campaign issue of -- threatens to sink Sherwood in a district so reliably conservative that Dems didn't field a challenger against him in the last two elections. As one pollster who's surveyed the race tells CQ: "The race in the 10th District appears to be primarily about two issues: Iraq and scandal. Unfortunately for Sherwood, neither issue helps him."
