Democrats’ big dilemma: Avoid Biden or embrace him?

The president and his political team have begun mapping out his election-year fundraising and travel schedule, according to Biden advisers, and he has shown great interest in the midterms — for example, talking to Sen. Robert P. Casey Jr. (D-Pa.) about the Pennsylvania race during a recent visit to the state, according to Casey. He also likes to hear from lawmakers traveling on Air Force One about what they are hearing and what they need, according to one Biden adviser, who, like others interviewed for this article, spoke on the condition of anonymity to more freely discuss the midterm campaign.
