The problem Ben Kenobi, is that you may have 50% who are pro-life, but some of which are in favor of Gay Rights. Some of which support big government. There is no 50% block that agrees with you on every issue 100%, Ben. That is my point and that is why your demanding strategy doesn't work. That is why you need moderation and nuance to at least some extent.
The other problem is that Mitt Romney is not who you claim him to be. He is at worst, a man without conviction. He is not pro-gay marriage and he is not currently pro-choice. I can understand not liking Mittens because he is a too politically exediant, but it makes no sense to oppose him on basis of a criteria which doesn't actually apply to him.
People don't vote for for one guy because the other guy didn't offer a contrast. They vote for the guy that offers the best vision for the country and/or plan to fix the countries problems. They will vote against someone they afraid to put in charge of Nukes or fear is too extreme.
You seem kind of moderate for your scores.
