America has always had a lot of religion in its politics but as the country becomes less religious they are demanding less religion in politics. It isn't the amount of religion that has changed it is our tolerance for that has changed. Look back at some of the speeches presidents and other politicians used to make. They talked about god a lot more then than now. Jimmy Carter taught Sunday School while he was in office and Clinton refereed to god more often than Bush did. It is a bit like the violent rhetoric we have been hearing so much about lately. It has always been there it is just the sudden media created illusion that makes it stand out. That is why it only stands out when consecrative say things like that and it is brushed off when liberals say, it doesn't fit the narrative. They have created the same false narrative that conservative are trying to create a theocracy so now every time a conservative mentions god it is like a dog whistle to the people who have bought into that narrative and they notice. They were ignoring it before and since the trust other liberals they ignore it in them having it brought to their attention creates the illusion of an increase.
