Keyes sure did a lot to stop Obama when he carpet bagged himself into the candidate against Obama’s pre-pre-Presidential campaign. Keyes actually made the previous choice of the Ill™ GOP - the Borg rejected name sake of their latest caught crook governor - look good by comparison. He should be treated as a fatal merger of Sgt. Schultz’s brains with Col. Klink’s ego.
If you wanted to find someone to run for office in an effort to intentionally turn voters against your own party and ideology, Alan Keyes would be that guy. Keyes really is one of the single worst political candidates I've ever seen in my life - and I've lived all over the world and seen LOTS of really bad candidates.
