Shhhh......else they will try changing the constitution instead.
That's exactly what they should be doing!
If the religious right want to turn the US into a theocracy or just have publicly funded religion, then they should be god-damn honest and campaign for that. They should campaign to have the separation of church and state abolished. They would still fail, but at least they wouldn't be engaged in the kind of dishonesty that currently characterises the pro-creationism-in-schools lobby.
