From a story on politico.com by Steven Shepard headlined “RFK Jr. goes independent. Does that hurt Biden or Trump?”:”

Robert F. Kennedy Jr. is poised to be the most formidable independent presidential candidate in more than two decades.

And already, operatives in both parties are moving to head off the impact.

A combination of his famous name and widespread voter dissatisfaction with both likely major party nominees puts him in position to earn the largest share of the vote for an independent candidate since Ross Perot drew nearly 19 percent in the 1992 election.
