Somebody is sending letters to pastors who are supporting Mike Huckabee saying that their activity is illegal.
According to the Des Moines Register:
Some Iowa pastors who support Republican Mike Huckabee for president say they have received letters warning them that getting involved in politics could endanger the tax-exempt status of their churches.
Several pastors who have publicly backed Huckabee, a Southern Baptist minister who has support from many evangelicals, said they have received the letters, which have no return address. They have arrived in the weeks leading to Thursday’s precinct caucuses.
This is clearly a political trip as the rules for pastors’ involvement in the political process are quite clear. Pastors may publicly endorse any candidate of their choosing, they just can’t use their pulpit to do so. They can encourage their congregation to vote and to be a part of the political process to go vote their values. They can provide non-partisan voters’ guides to those in their congregation that share where the candidates stand on different issues like abortion, gay marriage, poverty, education (or really whatever – it depends on who is providing the voters’ guide).
