In an interview with vanity Fair's Bob Colacello, Nancy Reagan talks about life after her husband, the Obamas and the Bushes. One snippet of analysis she gives about President Obama: he could have won political points by inviting her to attend his announcement of the executive order that ended the federal stem cell funding ban in March:

"I would have gone, and you know I don't like to travel," she tells Colacello. "Politically it would have been a good thing for him to do. Oh, well, nobody's perfect. He called and thanked me for working on it. But he could have gotten more mileage out of it."

Mrs. Reagan has long held that stem cell research has the capacity to deliver new cures, and she has publicly advocated on the issue.
