WASHINGTON (AP) — It’s a critical weekend ahead for President Joe Biden. Isolated as he battles a COVID infection at his beach house in Delaware, he is confronting the stark reality that many Democrats at the highest levels want him to consider how stepping aside from the 2024 election could be the party’s best chance of preventing widespread losses in November. Biden’s small circle of advisers has grown smaller as he weighs whether to stay in the race. His campaign is calling an all-staff meeting for Friday. And the Democratic National Committee is pressing ahead Friday with planning for a virtual roll call to nominate the president ahead of the party convention in August.
