There is no Batman in this race, but there is a Bane. See my other piece: Obama: The Bane of Capital
The democRats want to link Bane, the villain from The Dark Knight Rises, to Romney. As in "Bain" Capital. Now, Romney is no Batman, but Barack Hussein Obama is most definitely America's Bane.
bane: fatal injury or ruin. A cause of harm, ruin, or death. A source of persistent annoyance or exasperation. A deadly poison. A person or thing that causes misery or distress (esp in the phrase bane of one's life) Something that causes death or destruction. A fatal poison. Ruin or distress.
