If my memory serves me correctly- John Kasich was BFF w/ Gary Condit, when the two served together in Congress. The murder investigation of Chandra Levy, led to Condits' apartment in the DC area being searched with a fine tooth comb, due to an illicit relationship between Condit and Levy. Seems that (memory don't fail me now) one or more men's ties, were found tied to the bed frame of Mr. Condit. The apartments' every surface got the black light treatment in the hunt for clues like human dna. That detailed search "may have" led to further searches of friends and associates of Condits'.
I believe there was the usual (and typical) Wash., DC, hanky panky "alleged", and, shortly thereafter, John Kasich, announced that he was not running for reelection. Call me skeptical, but I can't help but think that the heat was too hot in the kitchen, or put another way, the- better get going while the getting is good notion, was the order of the day. I could see the Democrat smear machine gearing up for some good old fashioned astroturfing.
Your memory is spot on. This somewhat-glossed-over-at-the-time blip in Kasich's past is still really weird and mysterious....which makes it all the better (and juicier) fodder for Hillary's smear artists and the slavering drive-by media to sink their fangs into.
Unfortunately, while nobody is perfect, our candidate had better be purer than Caesar's wife, if you get my classical drift.
