Religion may not have a place in politics, or at least most of us agree it shouldn't, but it's difficult for it not to be. A persons religion and beliefs of any kind resonate in the decisions they make. Give somebody power over others as a politician? The presence of a religious belief or lack thereof is gonna be seen in their stances on certain topics. Most peoples' belief systems are founded on faith, or no faith. All their opinions and thought processes down the line are affected by it.
And I'm with Pangilian in my beliefs. Personally, I hate church and have never read the Bible. But I believe there is something out there that keeps us going.
