I understand your viewpoint. All I mean is that if you are only given two real choices (its a cruel, unfair world) then “reality” says we select the better of the 2 (or else get stuck with the Other). I didn’t invent the rules or they’d be a lot different.
But are we really given only two real choices? It's fear that says nobody else will vote for a third party, so my vote will be wasted. But if enough people stand up to that fear and vote third party, then what happens is the thrid party becomes one of the two dominant parties and the world is changed.
In my opinion there is not enough difference between the two candidates to worry if the other is selected. I think the checks and balances will work better if Obama is reelected than if Romney wins.
I reject the notion that a US Presidential Election is one of them.
