COMMENTARY | Republican presidential candidate Rick Santorum has come under some criticism for a comment he made regarding Barack Obama's Christianity or lack thereof. According to the Associated Press, Santorum said Obama's agenda is based on "some phony theology. Not a theology based on the Bible." He later said on "Face the Nation" he was talking about Obama's views on climate change and environmentalism. http://news.yahoo.com/rick-santorum-barack-obama-christianity-233600541.html
