Delaware Senate race moved to Lean Democrat

Christine O’Donnell’s upset over Cong Mike Castle in the GOP primary dramatically alters Republican prospects for November in Delaware. Castle had broad appeal, including to independents and even Democratic voters, while O’Donnell’s appeal is limited to tea party conservatives. Lacking an impressive resume and unlikely to garner significant national Republican support, O’Donnell clearly looks like an underdog against New Castle County Executive Chris Coons (D), who is suddenly transformed to the favorite in the general election. 

 
While tea party activists are jumping for joy at the primary results, it’s Democrats who will have the last laugh in Delaware. 
 
We’re moving the race from Lean Republican to Lean Democrat.
