House lawmakers on Wednesday overwhelmingly approved a final version of a bill that would give scientists in the state more freedom to conduct embryonic stem cell research, despite a promised veto by Gov. Mitt Romney. The bill was approved by a 119-38 vote. The Senate approved it by a 34-2 vote last week. Both votes give supporters far more than the two-thirds majority needed to override a gubernatorial veto. A final procedural vote is needed in both chambers before the bill is sent to Romney’s desk.It would let scientists create cloned embryos and extract their stem cells for research into the potential treatment and cure of diabetes, Parkinson’s disease, spinal cord injuries and other conditions.
