It has a republican holding, in each panel, a "support cain -- unlike the others, he's a real conservative", "support santorum -- unlike the others, he's a real conservative", etc, with bachman, newt, perry, etc, finally ending with Romney.

The subtext says something like, "tell me more about your conservative principles"

I saw it on FB a couple days ago, but can't dig it up now. I'm hoping someone's seen it, and can point me to it.
