The idea that you can be tax-exempt and still be involved in the political process is an abomination. To begin with, they should be paying taxes! They enjoy the benefits of infrastructure, police protection, fire protection… The list can go on forever. And they pay not one dime for those privileges. They should not get to be a part of the process of choosing who gets to be in political office. No one in public office should be beholden to a religious organization.
