You may be right. I don't think Romney would support Islam, but he could be anti-Israel. Mormon theology includes a line of thought that Mormons are the real Israeli descendants and not Israel.
I think I remember Romney making some pro-Israel campaign statements, but Romney's campaign statements are practically worthless due to his frequently employed etch-a-sketcher. And I'm not sure if as Governor he had an opportunity to have a real record on the matter.
I’m just tipping the balance as heavily as I can away from the “Romney is really an almost-Christian” meme, which right now is weighting down FR threads.
