We call it a stab in the back.  Members of the Kennedy family have endorsed President Biden for re-election,   a rejection of Robert F. Kennedy Jr.’s independent run for the White House.  More than 15 members of the famous political family gave their endorsement at a campaign event in Philadelphia.  Kennedy, the son of assassinated Senator and presidential candidate Robert F. Kennedy, is backed by 15% of registered voters, according to a recent poll.
