I think what happened in this case is Chandra forgot the rules of the game (or thought she was too hot for them to apply to her) and decided she wanted Condit all to herself, without having a clear picture of just what he was involved in. My guess is that she wasn't the one with whom he did the kinky stuff like the 'ridden hard and put away we' Ms. Smith, but just some 'fresh meat' for a few months, a situationally convenient toy. Very sad. When she decided to go for more, someone in the Condit world - I'm not sure if it was Gary, his wife, his kids, his staff, his sex club pals or outside help - decided Chandra knew too much and could cause too much trouble, so she was offed.
Er ... only pols cat around??????
The Clintons married *long before he went into politics* as well, and it is well-documented that she knew the guy couldn't keep it zipped for her, married him anyway.
