Is Age Too Great an Alzheimer's Risk for the Presidency?

Is Alzheimer's a concern for the upcoming election? Well, I would be concerned about the effects of the past drug use of Obama. Good question to ask - early onset dementia and other cognitive impairments are frequently a result of past drug use. When you see McCain and his 96 year old mother, you see two sharp, clear thinking individuals. Perhaps Obama assure the public by undergoing tests to show his competence.
