Drum reveals that he doesn’t know the subject matter with this P.S.: “By the way, who are these people who Ponnuru says are opposed to adult stem cell research? This is a genuine question. I’ve never heard of anyone taking this position.” Here’s what I actually wrote: “Some people object, for example, to funding research on non-embryonic sources of pluripotent stem-cell research.”

I wasn’t talking about adult stem cell research; I was talking about the creation of embryo-like entities that aren’t organisms. Sen. Harkin has voiced moral objections to that procedure, and 154 House Democrats voted against funding it. Adult stem cells aren’t pluripotent. That’s the reason his side of this debate thinks that research is inadequate. Do I have to brief Drum on his own argument?
