There’s a petition making the rounds on the White House website to remove “Under God” from the Pledge of Allegiance. It’s getting a lot of support… which, as you know, means absolutely nothing. The Pledge won’t change anytime soon. (If it ever does change back to it original form, you can bet it’ll be via the judicial system, not Congress or the President.)
But there’s no reason you can’t lend your symbolic support:
***Edit***: Apparently, there’s also an active petition to get “In God We Trust” off the currency.
