Sex sells. Why do you think the media latched on to Lewisnksy but ignored all the other (much worse) Clinton scandals?
First the tapes, which resulted in Linda Tripp being savaged by the media.
Then the Blue Dress with the DNA which the media could no longer deny.
Step three was defending infidelity and the MSM seceded there. We got history lessons on everyone from Thomas Jefferson to Dwight Eisenhower. (They stopped there never mentioning Kennedy of Johnson)
Never underestimate the MSM smog machine. They can obscure and confuse any issue no matter how blatant... if they feel like it.
