As far as I know, we have no (open) atheists in the chambers right now, despite Krysten Sinema being well known to refuse to identify with a religion. She has denied the label of atheist.
OP is out of the question for a long time, but were a state to elect an atheist Republican today, the states that would be the best candidates would be New England states.
What a coward.
Lol you never disappoint, TNF.
Shouldn't you be a little more focused on the individuals in the chambers who identify publicly as Catholics, Christians, Jews, etc. but are very likely atheists at heart? If she were truly a coward, she would be one of those people. I have no doubt she is being honest with the public about her religious beliefs.
