Candidate McCain's Health

Candidate McCain needs to be completely transparent regarding his health, if, for not other reason, to silence all the rumors circulating about his impending health disaster.  What is there to fear:  if his medical record confirms he is as healthy as he claims, we all win; if, however, it turns out he has serious health problems, as stealthily claimed by his doctors, then we the voters deserve to know to make an informed decision.
