Fluffy-bunny Christians, but not of the left

Yet again, we see members of various denominations that in other contexts might disparage or even flatly deny one another's Christianity -- in this case, Mormons and evangelical Protestants -- join forces for a supposedly Divinely sanctioned political cause. Having been called on doing so, they are now concocting elaborate excuses that essentially amount to backpedaling. If I didn't know any better, I might start to think that some people start with a secular ideology, or simply a lust for secular power, and then cherry-pick just enough Christianity to back it up.
