C'mon, Senator McCain. In the words of Dr. Seuss, "A person's a person, no matter how small". I really want to vote for you and your running mate Sarah Palin, but your endorsement of experimentation on embryos has been the major impediment to that. Let more barbaric technocracies play God with human DNA if they want. The U.S. needs to show real leadership on the issue by laying the foundation for an ethical bulwark against this insanity.
In this case, leadership means going against the grain - being the first lemming to turn around and head away from the cliff.
UPDATE: American Papist has more.
