What candidate wouldn't be thrilled to have thousands of his potential supporters meeting simultaneously around the state the night before the caucuses? Many evangelical churches hold family activities and services on Wednesday evenings, and Iowa churches are no different. The big question is whether pastors used the opportunity to talk up their brother-in-the-pulpit Mike Huckabee. A few churches have reported receiving anonymous letters warning that if their leaders get involved in electoral politics, they could end up in jail. But even if that’s enough to convince pastors to remain mum, the evangelical congregants who form the largest bloc of Huckabee supporters had the evening to chat with their undecided peers in between spaghetti suppers and hymn sings.
