The Caucus: Republican Candidates at the Citadel January 20, 2012, 8:46 pm Over on The Caucus, Ben Werschkul follows the Republican candidates to the Citadel, the military college of South Carolina. Candidates and presidents alike have long used the Citadel as a backdrop for foreign policy speeches. In the current campaign season, Republican candidates have also been recruiting young military men and women to volunteer for phone bank duty. Mr. Werschkul reports that Rick Santorum has been especially aggressive in reaching out to students. Cadet Alex Angerman of Egg Harbor, N.J., though unable to vote in the state's primary on Saturday, said that he made more than 1,500 calls for the former senator in the prelude to the primary.
