I think it would be more accurate to say that small churches are free to express more extreme political alignments, both conservative and liberal. Large churches have a lot of diversity within the congregation, making it difficult for the senior pastor to steer the whole community in a single direction. This would make them more moderate on average. They also have to worry about legalities such as maintaining a tax-exempt status, so they can't endorse a particular party or candidate too strongly.
