Adult stem cell research is already supported. It has a lot more promise than embryonic stem cell research at the moment, but since we have stem cell families derived from long gone embryos, the funding level is currently sufficient. If private researchers want to do more, they can find private funding. Private funding could double federal funding by just asking a few hollywood stars to toss a little bit of money into a research fund.
But as is typical of liberals - they'd rather spend tax payer money for a specific research project that most Americans would oppose if they understood the differences between adult stem cell harvesting and embryonic stem cell harvesting.
