2008 GOP platform calls for total ban on embryonic stem cell research, private or public.

Thinkprogress:

The 2008 Republican platform calls for “a ban on all embryonic stem-cell research, public or private.” The 2004 platform followed Bush’s policy of limiting federal funding for a restricted number of stem cell lines. The National Review’s Stephen Spruiell writes that the new platform language will read: “We call for a ban on human cloning and a ban on the creation of or experimentation on human embryos for research purposes.”
