Maybe it has nothing to do with sex but alot to do with the finances of Kerry. She may have overheard something or have the proof of something more damaging than sex. Illegal contributions? or payoffs? or....
More, from CBS:
"Sen. John Kerry, D-Mass.: Robert Farmer, 64, Clinton's 1992 treasurer and a longtime Kerry financial backer, is running Kerry's fundraising operation.
Farmer, the openly gay Clinton administration ambassador to Bermuda who splits his time between Boston and Miami Beach, worked for John Glenn in ‘84, was Mike Dukakis' chief fundraiser in '88 and DNC treasurer after that.
Longtime Kerry fundraiser Peter Maroney, who used to work for former Rep. Joseph Kennedy, is working with Farmer. Maroney was finance director for Kerry's PAC from 1999 until the presidential campaign officially started. Of course, the big question persists: Could John Kerry's real money person be his wife, ketchup heiress Teresa Heinz Kerry?"
