Well, yes, it is very complicated, but not for Mr Romney, who seems to be an odd combination of a 50s president, like Ike, and a right-wing nutjob like Dubya. It's not a good combination in my opinion.
Even more worrisome is that Mitt is neither of those things. I think he doesn’t have any core principles at all.
What makes me smile a little is that Mitt’s father kind of was an illegal immigrant. When the LDS church had it’s revelation that God no longer wanted anyone to practice polygamy which somehow conveniently coincided with the growing desire for statehood, Romney’s family fled to Mexico where they joined other polygamists. There is still a community there today which is increasingly criminal in nature. Then George Romney (Mitt’s father) and his parents came back over the border during the Mexican revolution.
Edit: The reason I say he doesn’t have core principles is that he espoused very different opinions and sponsored different programs when he was governor of Massachusetts including a government sponsored health care program.
