Jeremiah's latest ad is explicitly targeted at Christian voters:

He's got some more written and can shoot them, but money is holding him back. He has to shoot and edit these in his spare time, with his own money. Everyone else involved is generally volunteering, too. I don't know that there is anything unique about his ads as they relate to Huckabee, but they are IMHO the best TV ads I've seen yet supporting Ron Paul.
