The vote of 253-174, largely along party lines, fell short of the two-thirds majority needed to override a promised presidential veto. The measure passed after an emotional debate in which supporters touted the research as the best hope for potential cures for ailments such as Alzheimer's disease, diabetes, Parkinson's disease and spinal cord injuries. Opponents condemned it as unethical and immoral. Bush restricted funding for the research in August 2001. The stem cell bill now goes to the Senate, where supporters believe it will pass with a veto-proof two-thirds majority. The debate can transcend party politics, with some anti-abortion Republicans strongly supporting the research. Thirty-seven Republicans backed the bill on Thursday, while 16 Democrats opposed it.
