Here is what he said on Saturday regarding Christianity and the Constitution.
Later, McCain said, "I would vote for a Muslim if he or she was the candidate best able to lead the country and defend our political values." He added that "the Constitution established the United States of America as a Christian nation."
Wow, really? Because the actual U.S. Constitution says this (First Amemdment):
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof...
The bold piece is important - the Constitution explicitly forbids establishing the US of A as a Christian nation. This is of course in reaction to the feuds in Europe where countries like the United Kingdom are explicitly Christian (Anglican Protestant to be precise) by law.
I understand the need to pander to the Religious Right, but gee - making statements out of whole cloth is what Value Voters would call "lying."
