In what is seen as a move in a game of political one-upmanship, the Democratic Party has scored Ronald Reagan Jr. as a speaker for its National Convention later this month in Boston. Reagan is expected to speak about stem cell research.
Reagan has criticized the Bush administration's restriction of funding for such research, which he and his mother Nancy have argued could lead to cures for ailments such as Alzheimer's. The late president suffered the disease.
However, he will stick to the subject, he said: "If they had asked me to say a few words about throwing George Bush out of office, I wouldn't do it. This gives me a platform to educate people about stem cell research."
