Well, since he’s talking specifically to christians, in the context that he wants all christians to vote: he could have meant that he will fix all their concerns during his term – no more abortions, “christian values” in school, etc – so that next election, they don’t have to worry anymore. Just come out and vote this time, he’ll fix America so good that the liberals can’t even undo it if they win the next one (but they won’t, because everyone will be happy in this new golden age).
