If you don't believe Mr. Kincannon's source is legitimate then perhaps you might believe ex-Secret Service agents Gary Byrne:

and Ronald Kessler:

both of whom have written books in which they detail, from first-hand experience, Hillary Clinton's mental and emotional unfitness for office.

Then there's former head of the White House Military office, Col. Buzz Patterson, a man who resigned because of the things he saw the Clinton's do. This was a man who was with the President and first lady daily, who carried the Nuclear Football.

I've met the man and I have listened to what happened by someone who was there who went on record and whos story is almost identical to the others that have come out by former and current Law Enforcement, Secret Service, Military and Bill's bimbos.
