From the Orlando Sentinel:

The former Pennsylvania senator may be catching fire with the social conservative voters who also propelled Mike Huckabee to a surprise victory four years ago. Santorum has been lining up endorsements from prominent evangelical leaders, most notably former gubernatorial candidate and Huckabee backer Bob Vander Plaats.
According to the CNN/Time poll, 43% of likely caucusgoers say they can still change their mind.
