Fortunately here in Australia, we have had many many politicians who have been openly atheistic. We even had State Premier who was not only an atheist but quite openly Gay, or perhaps Bi, and was instrumental in bringing in many needed reforms in his state, reforms that were ultimately extended to all the other States and Teritories of Australia. That Premier was Don Dunstan of South Australia.

In Canada, our Minster of Science is an Atheist, as are at least 8 other cabinet members who chose secular swearing in as opposed to swearing on the bible.

Carolyn Bennett, Catherine McKenna, Jean-Yves Duclos, Carla Qualtrough, Hunter Tootoo are all openly atheist, and we have many secular politicians. I am glad I am Canadian!

Asheville, NC has a city council member, who after winning his election, was challenged because of his atheism. It was struck down in court. He is still on the council. Believe it or not the NC state constitution stipulates that any office holder must have a belief in the almighty. NC's constitution is not unique. However federal law trumps the states' idiocracy.

I'm not aware of any politician who is agnostic or atheist. It would unfortunately end that career. Sad.

Kristen Sinema from Arizona

The president of Greece. Mr Tsipras honest man He said in public, that He does not believe in god. Also the president of Holland, I hear one from UK can not remember name If I remember good, the one president from Croatia also. I am sure that some Americans politicians do not believe, but if not pretend that they are believers, most of the public are not going to vote for them.

Several are in the UK parliament right now. Most of those of faith keep it to themselves, but there are one or two who try (and sometimes succeed) in forcing their beliefs down the throats of their constituents. Nadine Dores in particular and it worries me that people continue to vote for these people - it's only party loyalty for the most part and that's why this system needs to change.

Charles Bradlaugh. He was a British politician in the late 1800's

Next year I will seek political office again like I did in the past. Last year I came in second! That was for state representative. Next year I will run for state senate. And I do NOT accept ANY contributions!!
