I think we should be a little more careful here. Just because a voter's 
vote has no effect on the outcome of an election does not mean that the 
vote has no effect.  By voting you are affecting the margin of victory 
or defeat. And vote margins still matter to politicians -- they signal 
whether the politicians are taking the right positions and making 
convincing arguments.
