NYTimes:

But in an interview on Tuesday, Mr. Romney said that he was strongly against a type of embryonic stem cell research that many scientists consider extremely promising: research that involves creating human embryos specifically for scientific experimentation.

The governor said he would oppose any bill, like the one Wednesday, that would allow that method. And he said he would propose his own legislation that would establish criminal and civil penalties for research like that being planned by labs at Harvard University and Children’s Hospital.

“Some of the practices that Harvard and probably other institutions in Massachusetts are engaged in cross the line of ethical conduct,” Mr. Romney said.

He added: “My wife has M.S., and we would love for there to be a cure for her disease and for the diseases of others. But there is an ethical boundary that should not be crossed.”

Keep watching Romney.
