Balkanization is kind of the point.
Right now you either vote for one of the major 2-4
candidates. If you vote for somebody who obviously won't get
elected then you feel
your vote was wasted so you just vote for
the lesser of two evils. You're
voting against a candidate you don't like rather then for one you do.
If we split
the major parties by writing in for people we actually
want to be
elected then our votes start to count.
When you give a blank ballot people see you don't like the choices. When you give a write-in they see that you don't like the choices
and they see what you
would like.
