Previously, I have compared and contrasted Newt Gingrich's lucid understanding of the threat posed by Sharia supremacism, versus Mitt Romney's muddled apologetic on jihad.

Last evening's (6/13/11) New Hampshire Republican primary candidates debate included a brief, but illuminating three-way exchange on Islam prompted by CNN moderator John King's query of Herman Cain.

Cain and Newt Gingrich were forthright and informed. But once again, Mitt Romney did not acquit himself well, revealing an unacceptable, utterly inadequate knowledge of the extent of documented Sharia encroachment in the US (see here, and here), coupled to politically-correct platitudes.

From the debate transcript:

KING: While we're on the topic of faith and religion, the next question goes to Mr. Cain. You recently said you would not appoint a Muslim to your cabinet and you kind of back off that a little bit and said you would first want to know if they're committed to the Constitution. You expressed concern that, quote, "a lot of Muslims are not totally dedicated to this country." Are American-Muslims as a group less committed to the Constitution than, say, Christian or Jews?

CAIN: First, the statement was would I be comfortable with a Muslim in my administration, not that I wouldn't appoint one. That's the exact transcript. And I would not be comfortable because you have peaceful Muslims and then you have militant Muslims, those that are trying to kill us. And so, when I said I wouldn't be comfortable, I was thinking about the ones that are trying to kill us, number one. Secondly, yes, I do not believe in Sharia law in American courts. I believe in American laws in American courts, period. There have been instances -

(CHEERS AND APPLAUSE)

CAIN: There have been instances in New Jersey -- there was an instance in Oklahoma where Muslims did try to influence court decisions with Sharia law. I was simply saying very emphatically, American laws in American courts.

KING: So, on that point, Governor Romney let me come to you on this.

What Mr. Cain is saying that he would have -- my term, not his -- a purity test or a loyalty test. He would want to ask a Muslim a few question or a few questions before he hired them, but he wouldn't ask those questions of a Christian or Jew.

CAIN: Sorry. No, you are restating something I did not say, OK? If I may, OK?

KING: Please let's make it clear.

CAIN: When you interview a person for a job, you look at their -- you look at their work record, you look at their resume, and then you have a one-on-one personal interview. During that personal interview, like in the business world and anywhere else, you are able to get a feeling for how committed that person is to the Constitution, how committed they are to the mission of the organization --

KING: When I asked -- I asked this question the other night, though, you said you want to ask a Muslim those questions but you didn't you have to ask them to a Christian or a Jew?

CAIN: I would ask certain questions, John. And it's not a litmus test. It is simply trying to make sure that we have people committed to the Constitution first in order for them to work effectively in the administration.

KING: Should one segment, Governor -- I mean, one segment of Americans, in this case, religion, but in any case, should one segment be singled out and treated differently?

ROMNEY: Well, first of all, of course, we're not going to have Sharia law applied in U.S. courts. That's never going to happen. We have a Constitution and we follow the law. No, I think we recognize that the people of all faiths are welcome in this country. Our nation was founded on a principal of religious tolerance. That's in fact why some of the early patriots came to this country and we treat people with respect regardless of their religious persuasion.

Obviously, anybody who would come into my administration would be someone who I knew, who I was comfortable with, and who I believed would honor as their highest oath -- their oath to defend and protect the Constitution of the United States.

KING: Mr. Speaker, go ahead.

GINGRICH: I just want to comment for a second. The Pakistani who emigrated to the U.S. became a citizen, built a car bomb which luckily failed to go off in Times Square was asked by the federal judge, how could he have done that when he signed -- when he swore an oath to the United States. And he looked at the judge and said, "You're my enemy. I lied." Now, I just want to go out on a limb here. I'm in favor of saying to people, if you're not prepared to be loyal to the United States, you will not serve in my administration, period.

(APPLAUSE)

GINGRICH: We did this -- we did this in dealing with the Nazis and we did this in dealing with the communists. And it was controversial both times, and both times we discovered after a while, you know, there are some genuinely bad people who would like to infiltrate our country. And we have got to have the guts to stand up and say no.
