I don't think this is about the inability to comprehend that there are gradations of evil in the world. I think this is at least in part the moral decision that some people take that they simply will not vote for ANY evil.
In other words sometimes the choices are so onerous they are impossible to make. If someone were to say "take this gun and kill one of your two children and if you don't kill one of them we will kill both", what would YOU do?
