running the khrafrbg iowa go to every county, organize every block kind of campaign, relying heavily on evangelical churches. trump is an unconventional candidate, not only in the way he is organizing but appealing. he is transcending some of the usual fracture we have seen. in the end trump kind of runs across these boundaries. he may prevent cruz from getting an advantage among evangelical christians we saw huckabee do in '08. i think he will still be very competitive. >> one of the interesting things is people can switch their party affiliation at the caucus site. they can do it out of a change of heart. in fact, the iowa gop chairman, jeff kauffman said the secretary of state confirmed 3,000 democrats who are unaffiliated have registered as republicans. so that is a whole new factor.
