Well Keyes wasn’t a real canddate anyway. Obama’s loyalists in the press illegally (IMHO) pried open his opponent’s sealed divorce records to drive him from the race.
Obama essentially ran unopposed in that election. In fact Obama may have lost the only election in which he faced real opposition - his specialty is using the legal process to get opposition candidates removed from the ballot.
Maybe he can find a way to remove McCain before the election. (Play the foreign-born card? :-))
