I've never associated Malkin with the Christian Right. The only claim to fame she's had, so far as I'm aware, is on immigration and being ripped apart by Matthews.
What I see are a few people with an agenda trying to manufacture a scandal to take down Laura Bush's poll numbers and give Christians and the Republican Party a bad name. Until someone can provide solid proof otherwise, I think the assessment is fairly accurate.
The only question is whether these agitators will be successful in their agenda.
There are a couple of sectors within the party. One sector is hard core RR. Another is a moderate evangelical sector. And then there are the secular conservatives who are pretty much party first. None of these sectors is 100% one way or the other. But for the most part, there is a pattern within them.
