Well I believe this was to use blastocysts that already exist, and are already frozen in storage. Blastocysts that will end up destroyed anyway. Why not save lives with these if they're going to be destroyed anyway? Unfortunately Bush doesn't see this.

And anyway, his whole theory on the issue totally expresses his complete hypocracy. He says we shouldn't destroy life to save life....yet, he's so willing to use military action in "pre-emptive warfare" to "save lives", even when over a hundred thousand civilians have died (oh but of coarse collateral damage is supposed to be expected).
