Under the banner of Evangelicals for Darfur, the leaders of two dozen Christian groups -- liberal and conservative alike -- joined forces today to run ads in several major newspapers demanding that President Bush "rally world leadership to put pressure on the government of Khartoum to stop this genocide."
