Would have kept Obama out of the White House. Those 8 years between Bush 43 and Trump would have been John Jr’s. Aging Boomers reliving their childhoods, Camelot, blahblahblah.
He was dead so the media had to go looking for a stand-in. The 70’s radical student left was moving into senior Establishment positions in the country and proffered two candidates— Hillary and Obummer.
Obummer’s strain of Democrat relied on government more than Hillary’s base did, so they had more riding on the outcome of the primaries (and general).
They swept the floor with Hillary, who took her pasty white ass back to Westchester and drank for two and a half years.
But I digress. Bottom line: JFK,Jr.’s death opened up a presidential possibility no one saw coming.
