The Biden campaign is insisting Biden will remain at the top of the ticket in November, arguing in a new memo that voters are still backing him despite concerns over his age and that the party has “no plan for an alternative nominee,” NBC News reports. From the memo: “While voters consistently mention President Biden’s age when contacted, our target voters — both re-engagement and true swing voters — are still planning to vote for him, making it clear the debate has not hurt support among the voters who will decide this election.”
