I read this article, and other sources, and found out that he is in favor of providing federal funding for already existing stem cell lines. The statement is not specific, but according to the way it's phrased, it sounds to me like he agrees with GWB concerning funding for already existing *embryonic* stem cell lines. This statement was on Huckabee's own website:
With respect to stem cells, I support federal funding of research using existing stem cell lines. I do not believe in creating life for the sole purpose of destroying it. I’m encouraged by recent discoveries showing that stem cells from the umbilical cord offer great promise.
