See Post 50. That will explain everything.
Your oft-cited post 50 does NOT explain why someone should support a candidate who does not even give LIPSERVICE to his party's platform. Nor does it offer any good reason to continually reward bad behavior in a politician or a political party. Because what is rewarded or subsidized is what you ALWAYS and without fail GET MORE OF. Rewarding a politician for trashing the Constitution (even if he does it a skosh less than his opponent) means that EVERY politician is going to be trashing the Constitution since no one will hold him accountable for doing so. Is THAT what you want?
If you want to surrender YOUR rights to the government, go right on ahead. If you try to surrender MY rights, well, you and I are likely to have more than just words about it. And by trying to get McGuiliRomney nominated above someone who HONORS the Constitution and its limits on governmental authority, you are making lots of headway in trying to give MY rights away. I take that rather personally.
