"Always vote for principle, though you may vote alone, and you may cherish the sweetest reflection that your vote is never lost."
Keep the faith. Vote your principle! And pay little if any attention to the GOPe bots. They have to vote their principles as well and that principle is winning at any cost. A poor principle indeed to guide folks through life.
Moral action requires examining the results of your actions.
Promoting the re-election of Obama is not high moral ground, and not a principled decision.
