If I were the Democrats, I'd say this.
"You will hear us tearing apart George W. Bush on every TV and radio channel, in the newspapers and in town meetings, unless Bush sends a letter to every hospital in the country and every major hospital in the world, saying that he now and forever refuses to avail himself of any of the medical advances resulting from embryonic stem cell research, as something that is against his freedom to practice his religion, and let him get everyone of those great Americans in the Bush family sign it too! Unless the Bushes are ready to back their "boy" why should anyone else back that lying hypocrite and his political stooge, Karl Rove."
