In favor.
One of our big strengths in this country is our ability to develop and research medical advances. We are going to lose our best scientists to other countries where they can do their research and develop their cures for diseases/disabilities and thereby lose a big chunk of our technological edge. If we have opportunities to cure diseases and disabilities, thereby saving real, living, breathing human beings, why wouldn't we do it? To save frozen embryos which will be thrown away?
Politicians who are against allowing more stem cell lines say we have enough. The scientists who are actually doing the research don't agree and claim that many of the current lines are corrupt and unusable. I tend to believe those who are actually educated in this area and understand the science behind it.
Besides, I work for a biostatistics department and need research to keep happening here in the US of A so that I can keep my job
