That's the joke, you know 'the third rail in politics'. Well the unspoken 4th pillar is religious identification.
I'm more like the framers, in the 'r' thinking. Taking a cue from Carlin the "professional Christians" (Lou Dobson, Pat Robertson etc) think the framers created a Christian Nation in the glory of God that will last forever. Seriously, I get emails about the 'Christian' meaning on top of the Washington Monument. etc.
