Didnt say his campaign was anti-religious, but his stance is much different on God and religion then any of our past presidents would be. At least their stated stance (whether the lived what they said is a different story), and I think he attracts people who are disinterested in or ‘fear’ religion. - Which might be ok, I dont need someone to fake a religious world view.
I think it plays well to most of his base that “god” isnt really part of his platform.
