It’s a trick question with an impossible answer: If Famous Person A hadn’t died would Famous Person B still be as famous? But that doesn’t stop folks from digging up the imaginary measuring stick. Take, for instance, RoseMarie Terenzio.

In the latest issue of People magazine, the John F. Kennedy Jr. confidant claims that if Camelot’s heir apparent hadn’t died in a 1999 plane crash then Barack Obama would not have made it to the White House nearly a decade later.

“Someone once asked me if John were alive, what would he think of Obama being elected president, and I responded if John were alive, Barack Obama would not be the president,” said Terenzio, Kennedy’s friend and former assistant. Kennedy was piloting a light aircraft carrying his wife, Carolyn Bessette Kennedy, and her sister Lauren Bessette when it crashed in the Atlantic Ocean off the coast of Martha’s Vineyard on July 16, 1999, killing all three.

“John would have gone into politics by now,” added Terenzio. “He was approached to run for the Senate before Hillary Clinton joined the race.”

When Terenzio’s memoir about her glamorous life with the Kennedy couple, “Fairy Tale Interrupted,” was released in 2012, she told the Reliable Source that George magazine, which was co-founded by Kennedy, was ahead of its time “with tea parties and hanging chads and Obama.”
