They ALL were in favor!
Perhaps you mean that highly ineffective and morally troubled line of research known as "embryonic" stem cell research.
Most of the responders named "Adult" stem cell reseach -- and that is a far, far more promising and already practical and demonstratively effective line. I don't remember any mentioning umbilical cord cells -- Romney was pushing cell nuclei transplants -- I'm not familiar with that subject.
Thanks! You were right. I was referring to embryonic. I support adult fully, but I am opposed to embryonic. Do you know which candidates opposed embryonic?
Both Rooty and McCain said they would be ok with funding embryonic stem cell research.
