No, it was about Dick Nixon sweating whether Ted Kennedy was secretly preparing to jump into the Democrat nomination race that year (1972). He'd have been a threat to Nixon (who'd been beaten by Jack Kennedy), even with the Chappaquiddick thing hanging over his head.
As it turned out, the working journalists who were surveyed about their votes, answered that they'd voted 9:1 for George McGovern, in the teeth of a national landslide for Nixon. So Nixon was right to worry about Kennedy, who'd have had the media jump instantly to his side had he declared.
