You are correct. Romney is not the constitutional stickler that I am. However, if presented with the choice of Romney or Obama, Romney has to be my choice. The lack of popularity of third-parties in the United States make it, essentially, a wash to vote for any of them. A vote for a libertarian candidate who isn't going to win is as good as a vote for Obama.
Now, I did say that Romney is only the beginning of, what I hope would be, a process of returning the country to the Constitution. A hardcore libertarian would be the wrong choice right now because that kind of dramatic shift would not be good for the country, as I stated earlier. We need a smooth and slow transition back that direction and its going to take several presidents to do.
With all that said, Romney may have some differing motives, but I think in many ways we have the same process and ends in mind.
For example:
The most important thing to me in this election is economic policy. Primarily domestic, but foreign as well as it pertains to domestic.
Currently, the national government interferes too much with the lives of its citizens. This is a fundamental break with the Constitution.
Romney, while I'm sure he sees this same break, he views the same issues from the standpoint of a businessman. He sees bloated agencies that duplicate/triplicate existing state/county/local agencies. The government is wasting millions, if not billions, of dollars performing these duplicate functions.
We both see the need to cut down the government bureaucracy.
Now, you refer to a number of policy changes and flips. Would you care to expand on that? I've heard of some, but I've been satisfied with the explanations.
I think Romney has a backbone, he just hides it well. He knows when he needs to be firm and decisive.
As for Romney's soul, if I'm getting your meaning, I must completely disagree. Mitt Romney is among the most charitable people I think I've ever heard of, not just with his money, but his time as well. I've heard some absolutely amazing stories about him. Its never talked about because he doesn't toot his own horn.
