"Had Senator Sanders won the day with his refusal to support and invest in stem cell research, Americans would have lost access to a new frontier of medicine that could one day cure Alzheimer’s, ALS, and other fatal diseases," Doyle said in a statement. "When medical progress needed support from Sanders, he not only was absent, but was among those leading the effort against it. This is in stark contrast to Hillary Clinton who in the Senate successfully fought to expand funding for the National Institutes of Health and has consistently supported stem cell research and its potential to save the lives of Americans and their loved ones."
