Last week, Monitor Mix proposed a new (unscientific) method to help decide who Barack Obama and John McCain should choose as their respective running mates. First, readers were asked to imagine who each presidential candidate would be if they were a band or musician. Then, readers suggested vice presidential choices a.k.a supporting acts that would help the headliner and appeal to the most people.The following options are culled from their responses. Please vote for the strongest line-up.
