According to the last two PPP polls (12/27) and 1/1), nine out of 12 Iowa evangelicals who have changed their preference in the last few days have moved to Santorum. Most of them have come from Paul and Bachmann (who have shed 22 percent and 27 percent of their evangelical support respectively). Santorum now has a quarter of the evangelicals in his corner.
Meanwhile, evangelicals have crept up to nearly 50 percent of likely caucus attenders. With the former Pennsylvania senator (18 percent) in a statistical tie with Paul (20 percent) and Romney (19 percent), a continuation of the Santorum Surge will put him over the top–and by a hefty margin if the church buses roll.
