It’s not just frum people. Most religious people are Republican/Conservative. (with the possible exception of Muslims).
Without going into some of the many other reasons the Democrats and liberals are becoming increasingly hostile to religion. The pundits wonder why the evangelicals support Trump even though he isn’t even nominally religious in his personal life. The answer is simple. Much as Trump makes fun and insults other people, one group he NEVER starts up with or makes fun is religious people or religious leaders.
Yes Obama is a family man who went to church for twenty year listening to Jeremiah Wright deliver his message of hate. But when he talks about “clinging to guns and religion” instead of joining his enlightened crowd, when he tried t force Catholic employers to violate their religious principles it’s easy to understand why religious people don’t want his ilk in office.
