What does cloning do to the stem-cell debate?

OK, so the whole stem-cell debate in congress mostly revolves around the fac that, as Bush put it, “…extracting the stem cell destroys the embryo, and thus destroys its potential for life,” and opponents of embryonic stem-cell research suggest scientists should focus on adult stem cells that don’t have that potential. Which just makes me wonder, what happens if (or when) science advances to the point where human cloning is possible? Would adult stem cells be verboten as well? What happens when blood cells and dead skin have the “potential for life?”
