Why are we not farming politicians who have the integrity to say, no, I'm not a believer in religion?

I'm not saying be disrespectful. What I'm saying is that policies created by and adopted by our institutions of civic governance make a difference to humanity. Policies in the US are generated out of a democratically elected political system of government authority. The political process that puts these people in power, and influences their actions, is flooded with money from unabashed religious organizations - which are a big part of the problem for humanity because they foster unproductive mindsets.

I am looking for institutions and foundations, which I can contribute to, that are/will counter the big money religious ones. Institutions that also promote political candidates that proudly and without any hesitation, acknowledge that they are A-theistic - because reason, logic, and scientific knowledge is what is real, and religion and magical gods are not (Just like religious organizations are doing in the other side).

I ask, is there such a thing?
