Did Ronald Reagan Have Alzheimers While He Was President

 One of Ronald Reagan's sons has claimed the former President had Alzheimer's disease while he was in office. On CBS's Early Show, Michael Reagan said the claim by his brother Ron-- was just that-- a claim. He said "there's no evidence anywhere on the planet to back it up." Ron Reagan said their father looked lost and bewildered during the 1984 presidential debates. Michael disagrees. He says he was overloaded with facts and figures-- and in the next debate, took Walter Mondale "to the cleaners." Michael Reagan said whether he had the disease then or not-- it should not tarnish his father's history as President.
