You're correct he wasn't running yet. Perhaps they knew he would win though?
John F. Kennedy Jr. did run for a Senate seat. He was considering a run for the U.S. Senate in New York in 2000. However, he tragically died in a plane crash on July 16, 1999, before he could officially announce his candidacy or enter the race. His potential candidacy was much anticipated and would have been a significant event in U.S. politics, given his name recognition and the legacy of the Kennedy family.
If John F. Kennedy Jr. had run for the U.S. Senate seat from New York in the year 2000, he would have been running against several candidates, but primarily against:
Hillary Rodham Clinton for the Democratic Party. Clinton won the election, becoming the first First Lady to run for and win public office.
Rudy Giuliani was initially considered a frontrunner for the Republican nomination but dropped out due to health issues (prostate cancer) and personal reasons.
Rick Lazio ultimately became the Republican nominee after Giuliani's withdrawal. Lazio was a U.S. Representative from New York.

Grok. I don't have all the answers but I know Q has access to classified material unlike us.
