This is a good idea, with very little chance of success – the religious verbiage was added as an opportunist knee-jerk reaction during the commie scare, and the same should hold true for the removal of ‘under god’ from the pledge of allegiance.
Basically, “e pluribus unum” is a far better motto than “in god we trust”
Do we need religious verbiage on our money?
