Is the USA being taken over by right wing evangelical Christians?

Just to let you in on a little secret all US presidents have been Christians. Unless you believe the web chatter that President Obama is Islamic. Also another little secret the people who wrote the constitutions were all Christians too. You live in a county that is mostly Christian yet you live in freedom and can be openly atheist because those silly Christians believe you have the right to believe what you want because freedom is a God given right.
