There's still a large number in our society who believe you shouldn't mix religion and politics. This notion has always been slanted more to mean that clergy shouldn't express political opinions, rather than politicians making religious assertions. Rev. Jeremiah Wright's recent rocketing notoriety has inflicted his liberation theology (a mix of Marxism and Christianity) on all of us and would certainly lend credence to clergy staying out of the political realm. However, when politicians try to borrow from the Bible to support their agendas, most of the time they mess up!
