Ever hear of representative self-government?
At least I represent those who will be voting for me.
Rare indeed is the Romney supporter who will admit that he represents them.
Ever hear of ‘the ends justifies the means’? Well, in this case, there is no justification for re-electing Obama because votes were cast for you, or any other third party wasted vote. The result would still mean Obama is re-elected, and that cannot be justified in God’s book.
