"We’re not accustomed to asking such questions about our presidents. We don’t know how to even begin inquiring into a president’s mental health..." 

Really? 

Robinson doesn't recall that top aides of LBJ consulted psychiatrists because of his emotionally erratic behavior? 

The media's play by play of Nixon's paranoia? 

The hints that Ford's famous clumsiness was a result of brain damage? 

Reagan being diagnosed with Alzheimer's by the media PRIOR to his first election? 

Bush the Younger's imbicility due to alcohol and drug abuse? 

"We’re not accustomed to asking such questions about our presidents. We don’t know how to even begin inquiring into a president’s mental health..." 

Yeah, right.
