Romney Can't Give Straight Answer When Questioned About His Mormon Faith

I frankly don't care what religion a man is when I vote on public office candidates. Yes, there a lots of evangelical Christians who believe that the Mormonism of Mitt Romney is akin to a cult, but are still willing to consider his qualifications to become president.
But one thing that irks me about Romney (among many other things) is his lack of authenticity. He doesn't seem to have a set of settled principles aside from saying anything to win votes.
No where was that more present than his interview on a Birmingham, AL, talk show. Here is a video clip of the interview:

Here's part of an account on the interview:

The hosts of the Birmingham-based radio program, Rick Burgess and Bill Bussey, pressed Romney on his Mormon faith, asking him if he believes the United States reigns over Israel as the true Judeo-Christian "Promised Land." The Book of Mormon teaches that America is a "land of promise."
"Do you as a Mormon believe that America is the new 'Promised Land,' yes or no?" asked Burgess.
"You're gonna have to go to the church and ask what they think about that," Romney responded with a laugh, referring to the Church of Jesus Christ of Latter Day Saints, of which Romney is a member.

Why couldn't Romney give a straight yes or no answer to the question? Is he THAT insecure about who he is that he couldn't give a straight answer even if there was a possibility that whatever he said could cost him votes?
This is the same Mitt Romney who is bold enough to lie about President Obama's positions ('here's one example), but is so cowardly when it comes to standing up to the woman-hating Rush Limbaugh. 
He won't stand up to Rush Limbaugh, he'll say anything, including lie, to gain votes, and he is also willing to change his position no matter how bad he looks doing it. Is this someone you'd want to be president?
I say H--- no.
