In OTL, before the post-Viet Nam and post-Watergate era of the 1970s, journalists generally did not report about the extramarital sex lives of politicians (assuming the politicians were at least somehwat discreet). There were numerous married politicians in Washington D.C. (besides JFK) and the state capitals have affairs with other (and younger) women, but it neither appeared in the newspapers nor was broadcast on the radio or TV. Many reporters were very familar with the various rumored extramarital affairs of President Kennedy--he was rather recklessness about his liasons--but they liked JFK and generally didn't report about such matters anyway.
What if women publicly came forward about their sexual relationships with JFK in 1962 or early 1963--perhaps the unstable Marilyn Monroe and a young White House secretary or two--and mainstream media outlets actually began reporting about it?
