Why would it even be strange, that many atheists are leftist, especially in USA. Conservatives wipe their d*cks with the bible all the time, because that's the best tool at their disposal, for brainwashing the poor and the uneducated into voting against their own interest. As long as conservatives (be it Republicans, or any similar factions in Europe) need to pander to stupid people, promote social inequality ad impede progress - I know I'd want nothing to do with the c*nts, even if I did agree with their fiscal policies.
