I think your way high on the agnostic community being anywhere close to 25% of the US population. I’ve lived here in western Oklahoma all my life and only have 2 openly atheist friends. Here where I live people were so disgusted with the democrats Trump carried my hometown with 87% of the vote and all 77 counties in my home state with about 70% of the vote. Even though I am atheist and don’t like the religious influence in the Republican Party I fully support Trump as I think the country will do a lot better as he’s a businessman and knows how to stimulate the economy. The overwhelming majority of the religious people are just practicing religion because of tradition anyway so I have no problem with most of them.

Not everyone who voted will come from the US. I, for example, am from the UK - and this will skew the numbers negatively since I don't know anyone outside of the US who thinks he's doing a good job - everyone I talk with think he's a vile piece of scum as both a human being and policy maker.

Although the list is from 9/19/2013 there are atheists in Congress.

As far as I know, unless it's changed in the last year or so, there are no openly atheist or agnostic representatives or senators in the U.S. Congress. There was one a few years ago — I forget his name — who had served many terms but wasn't public about his non-theism; he came out of the atheist closet and lost his next election. If anything, I figure the actual percentage in Congress who lack religious faith is probably higher than in the general population, but it's still seen as political suicide to openly acknowledge it.
