Reagan says his family feels particularly alienated from the Republican Party over its opposition to embryonic stem cell research, which could have significant benefit for Alzheimer patients like his father. "Now ignorance is one thing, ignorance can be cured. But many of the Republican leaders opposing this research know better, people like [Senate Majority Leader] Bill Frist, who's a doctor, for God's sake. People like him are blocking it to pander to the 20 percent of their base who are mouth-breathers. And that's unconscionable -- there are lives at stake here. Stem cell research can revolutionize medicine, more than anything since antibiotics."
