US Republican presidential candidate John McCain, who has previously called for ending the Bush administration's ban on financing embryonic stem cell research, now seems to be calling for it to be extended.
"He cannot be trusted to be a supporter of embryonic stem cell research," University of Pennsylvania bioethicist Art Caplan told Wired magazine. "He is moving toward a straight pro-life stance and this sort of answer can only be read as such."
Responding to questions posted by Sciencedebate2008, McCain said, "I believe clear lines should be drawn that reflect a refusal to sacrifice moral values and ethical principles for the sake of scientific progress."
Wisconsin bioethicist R. Alta Charo called it "a close echo of Bush's language used to support the ban on funding for work with newer lines."
Democratic candidate Barack Obama called for an end to the US federal funding ban.
