This reminds me of the Citizen Kang episode of The Simpsons:

“It’s true. We are aliens. But what are you going to do about it. It’s a two-party system. You have to vote for one of us.”
“Well I believe I’ll vote for a third-party candidate.”
“Go ahead, throw your vote away.” *Alien Laughter*

and the classic line from Homer:
"Don't blame me, I voted for Kodos"
A humourous phrase uttered by Homer Simpson during an arguement with Marge after their planet has been overrun by aliens and all humans had been pressed into slavery. Homer is suggesting by this statement that the world would be a better place if the rest of the world had voted Kodos (another alien) into power. In truth if either alien had been voted into power the outcome would have been the same.
