While we don’t know exactly, I think it might have been something like a never ending cycle of a grim, despondent, headlong rush over a cliff and into the quarry, with no happy ending or any dawning awareness of the main character.
Or, as Mitt says, a preparation.
Which, come to think of it, isn’t such an awful ending after all. Barack Obama might be merely the lesser of two, or in this case, three evils, but Mitt and Newt are…EVIL. Evil with a Walter White/Heisenberg meth level of purity.
