President Joe Biden will accept endorsements from at least 15 members of the Kennedy political family during a campaign stop in Philadelphia as he aims to undermine former President Donald Trump and marginalize the candidacy of Robert F. Kennedy Jr. The decision to highlight the Kennedy family endorsement on Thursday, more than six months from Election Day, is an indication of how seriously Biden’s team is taking the threat of the independent bid potentially using his last name’s lingering Democratic magic to siphon off support from the president. Both Democrats and Republicans worry that Kennedy’s candidacy could spoil their respective presumptive nominee's campaigns.
