Charles Krauthammer nails it. Key paragraph:

Science has everything to say about what is possible. Science has nothing to say about what is permissible. Obama's pretense that he will "restore science to its rightful place" and make science, not ideology, dispositive in moral debates is yet more rhetorical sleight of hand—this time to abdicate decision-making and color his own ideological preferences as authentically "scientific."

President Obama frames the debate over embryonic research as one between science and morality. It's actually between two conceptions of morality. Either Obama knows this or he doesn't. If he does, then he's being intellectually dishonest. If he doesn't, then he's not very intelligent.
