I never thought they meant it, but for quite some time most "respectable" people pushing the "Christian Nation" crap usually managed to pay some lip service to "Judeo-Christian" so it wasn't quite as obvious that they're exclusionary bigots.
The God talk in politics quieted down for a bit, but if we're going to go down this path again it's time to cut the can't-we-all-get-along ecumenical stuff and start talking disagreements. Does Mittens qualify under Radical Cleric Gingrich's definition of Christian?
