I wonder if they would favor it if they know about the problem with tumors and that the supposed answer to tissue rejection is human cloning. Note also in that poll that people oppose cloning humans by an overwhelming margin, and also oppose cloning animals. This is why proponents of therapeutic cloning never use the C-word in reference to research, but still use it in reference to babies. This despite the fact that cloning, is cloning, is cloning (or somatic cell nuclear transfer is SCNT, is SCNT). There is but one act of cloning. After that it is only a question of what is done with the new human life that has been created.
