It's a national election. Whoever is elected should be via the total national vote.  If the individual people in each state vote, and total the votes from each state end up with a majority being red, blue, green or whatever, then so be it.  That's the will of the voters. If any party wants to increase its numbers, it'll have to work to A, Get more individuals to join their party B.  Get off their asses and vote. 
I want my vote to count. It rarely does.
