So many pastors are scared poopless when it comes to anything political. Therefore, they allow no voters guides or anything that might be remotely seen as political in their churches. Nine out of ten pastors would not allow it. The church has become anemic and pathetic as a whole, not because of the laws, but because of wimpy pastors who are too scared to take a stand. And it isn't just pastors.
Pews are full of wimpy laymen as well.
I know of rare pastors who say free speech will be practiced in their pulpits and that includes politics. Most families do not give enough to itemize their taxes, anyway. And ineffective is what the church has been of late. Would that God's Spirit would get inside more pastors and laymen and give them backbones of steel. The Bible says that the body of Christ is made up of many members.
