If you've opposed federal funding of [embryonic cell] research on the grounds that embryos shouldn't be killed, biopsy solves your problem. The only people bound to oppose biopsy are those who 1) oppose [in vitro fertilization] because it's artificial or 2) object to exposing embryos to the same risks involved in [pre-implantation genetic diagnosis]. The billion-dollar question is which way President Bush will go. His past statements indicate that his concern is embryo killing and that he's looking for a way forward. Both factors suggest that he'd allow funding of research on ES lines derived from biopsy.
