If Embryonic Stem Cells are okay, why isn't Cloning?

Maybe I have read too much science fiction, but President Obama's latest order on stem cells seems self-contradictory to me. On the one hand, he endorses the use of embryonic stem cells - a moral issue for those who believe embryos are "human life" where embryos may be created and destroyed to harvest stem cells. On the other hand he condemns the use of stem cells for human cloning.

Obama also said the stem cell policy is designed so that it "never opens the door to the use of cloning for human reproduction." Such cloning, he said, "is dangerous, profoundly wrong, and has no place in our society or any society."

The statement that cloning is "profoundly wrong" is made without any defense or philosophical rationale. He simply assumes it is obvious. But it is not. If you are not worried about "human life" in embryos, how is cloning different from producing twins from current fertility techniques? (*cough* octo-mom *cough*) Can anyone out there explain this to me logically?

Or is it just that to Barack Obama stem cell research "feels right" and cloning "feels wrong"?
