Pelosi always plays the 'God Card' when she feels she is about to lose something. She is a 100% secular Leftist 99.9% of the time. But whenever she feels she can gain something from religion, or manipulate the foolish religious people, she transforms into Mother Teresa and tries to convince everyone that she is an outlet of God and is doing his work.
She is a class A manipulator. And if 'God' comes in handy once in a while, she does not hesitate to use him to further her Leftist goals.
