In a pair of Friday events — a campaign rally in the battleground state of Wisconsin and a prime-time interview on ABC — President Biden dismissed concerns about his fitness to continue his campaign and stated he intends to remain on the ballot in November. When confronted with calls from Democratic lawmakers, donors and voters for him to withdraw from the race, the president said that only “the Lord Almighty” could make him change his mind. It remains unclear whether his full-throated insistence on continuing his campaign will be enough to allay party concerns.
