There are rumors floating on the Web about McCain's military service, including his actions while a POW, and his political career and personal life. We know about the story The New York Times published about his alleged business and social connections with a female lobbyist. The story as published had about as much substance as what you would read in a supermarket tabloid. However, if there is a "smoking gun", dirt dating back to the Keating Five days, or some disgruntled POWs wanting to be this election's Swift Boat veterans, rest assured that the Clinton smear machine will exploit it to the hilt.
Back in 2000, there were reports that McCain was brought up on Congressional ethics charges for having raped the wife of a former POW at some party. Apparently nothing came of the charges because McCain claimed that the woman was drunk and came on to him. The woman claims that she doesn’t drink or do drugs, so she could not have been drunk, a he said, she said, about an accusation where no charges were brought within the statutes of limitation. All references to this attack have disappeared from the internet, but as I recall, Maureen Dowd wrote a story about in during the 2000 election season. This will surface again, later in the election cycle, if it is indeed a matter of congressional record.
