Sen. Kamala Harris soared after her strong performance following the first Democratic presidential debate, but recent polling suggests that her boomlet has run its course.

To be sure, Harris is still polling better than she was before pummeling Joe Biden in the first debate, but she’s retreated from the highs she was experiencing in the immediate aftermath of that mauling. Specifically, after the debate, Harris jumped from around 7% in the RealClearPolitics average to 15%. But she subsequently sank to about 12%. A few weeks ago, it seemed as though she was surging into the second place position, now she’s basically in a traffic jam with the other candidates chasing Biden — Sens. Elizabeth Warren and Bernie Sanders. It’s not a terrible place to be at this early stage in the race, but it does suggest some resistance.
