Harris Has a Lot of Strengths. Giving Interviews Isn’t One of Them.

The first question Vice President Kamala Harris faced on Wednesday night, in her first solo interview with a major cable network as the Democratic presidential nominee, was posed as a gentle hypothetical: What would she say to the many Americans who do not see how her economic policies would serve them?

“Well,” Ms. Harris began, shaking her head, “if you are hardworking, if you have the dreams and the ambitions and the aspirations — of what I believe you do — you’re in my plan.”

She paused and smiled.

“You know, I have to tell you,” she said, eyes lightly closed, hands raised, “I really love and am so energized by what I know to be the spirit and character of the American people.”

In her dizzying ascent to the top of the Democratic ticket, Ms. Harris has proved to be a disciplined and effective debater and a tireless campaigner, nimble and energetic in rallies. But one-on-one televised interviews with journalists have long been a weakness in her political arsenal. She often winds her way slowly toward an answer, leaning on jargon and rehearsed turns of phrase, using language that is sometimes derided as “word salad” but might be better described as a meringue.

As a presidential candidate, Ms. Harris has largely eschewed such interviews, a calculation by her campaign that she can reach more of the voters who matter through town-hall events with celebrities, local television spots, curated videos and social media, without the risks of a prime-time spotlight.

But the avoidance also appears to reflect something deeper, a nervousness that is palpable from the moment Ms. Harris takes her seat across from an interviewer, looking as if she were bracing for a hostile cross-examination — from the witness stand.
