Stem cell laws and policy in the United States
In 1973, Roe v. Wade legalized abortion in the United States. Five years later, the first successful human "in vitro" fertilization resulted in the birth of Louise Brown in England. These developments prompted the federal government to create regulations barring the use of federal funds for research that experimented on human embryos. In 1995, the NIH Human Embryo Research Panel advised the administration of President Bill Clinton to permit federal funding for research on embryos left over from "in vitro" fertility treatments and also recommended federal funding of research on embryos specifically created for experimentation. In response to the panel's recommendations, the Clinton administration, citing moral and ethical concerns, declined to fund research on embryos created solely for research purposes, but did agree to fund research on left-over embryos created by "in vitro" fertility treatments. At this point, the Congress intervened and passed the Dickey-Wicker Amendment in 1995 (the final bill, which included the Dickey Amendment, was signed into law by Bill Clinton) which prohibited any federal funding for the Department of Health and Human Services be used for research that resulted in the destruction of an embryo regardless of the source of that embryo. In 1998, privately funded research led to the breakthrough discovery of human Embryonic stem cells (hESC).
Political positions of John McCain
McCain was a member of The Republican Main Street Partnership and supported embryonic stem cell research. McCain had earlier opposed embryonic stem cell research and credits former First Lady Nancy Reagan, a prominent Republican supporter of such research, with changing his mind in 2001. He states that he believes that stem cell research, and indeed embryonic stem cell research, will continue whether or not the U.S. sanctions it, and so it would be the wisest course of action to support it to the extent that the United States will be able to regulate and monitor the use. In July 2008 he said "At the moment I support stem cell research [because of] the potential it has for curing some of the most terrible diseases that afflict mankind."
