A
voting system wherein you cast a
vote for each
candidate you think is
capable of
doing the
job, or, put another way, each candidate you would
like, or not
object to, having the job.
This system is nice because you don't have to worry about wasting your vote. Torn between Gore and Nader, or Buchanan and Bush, or whatever? Vote for 'em both. Think either Gore or Bush would be fine but don't think any of the third-party turkeys can do the job? Vote for both Gore and Bush.
The winner is whichever candidate gets the highest approval count.
An advantage of this system over instant runoff elections is that you don't have to worry about playing games with your ordering; a disadvantage is you can't provide any information with your ordering.
