Since they are the least worldly, and most conservative voters in America and deliver 80% of their vote for pro-life and conservatism. I think that we can count them as ""a clear example of a religious group that is solidly conservative"".
Actually, I guess America' second largest church denomination (Southern Baptist) could be slightly to the right of the catch all (mass) category of "Evangelical".
......”they (Evangelicals) are the least worldly”.....
Imo there is nothing solid today....everything is in motion including the Evangelical Commmunity. The fact so many Rhinos are elected attests to the fact conservatives are not as many as one wants to imagine.
