New Poll Suggests Harris’s Support Has Stalled After a Euphoric August

Almost 30 percent of voters said they needed to learn more about her.

Is Kamala Harris’s surge beginning to ebb?

That’s the question raised by this morning’s New York Times/Siena College poll, which finds Donald J. Trump narrowly ahead of her among likely voters nationwide, 48 percent to 47 percent.

To me, the result is a bit surprising. It’s the first lead for Mr. Trump in a major nonpartisan national survey in about a month. As a result, it’s worth being at least a little cautious about these findings, as there isn’t much confirmation from other polls.

That said, it wouldn’t be hard to explain if Vice President Harris’s support really has faded a bit in recent weeks. After all, she was benefiting from an ideal news environment: an uninterrupted month of glowing coverage from President Biden’s departure from the race in July to the Democratic convention in August. It’s possible she was riding a political sugar high; if so, it would make sense if she came off those highs in the two uneventful weeks since the convention.

There’s also a plausible reason the Times/Siena poll would be the first to capture a shift back toward Mr. Trump: There simply haven’t been many high-quality surveys fielded since the convention, when Ms. Harris was riding high. There was a scattering of online polls this week, but there hasn’t been a traditional high-quality survey with interviews conducted after Aug. 28.
