Since late July, when Joe Biden deep-sixed his campaign, the Trump brain trust in Mar-a-Lago has been struggling to land decisive blows against Kamala Harris. The vice president should be an easy target, these people have grumbled, given her No. 2 role in a pretty unpopular administration. But Harris, thanks to a flawless campaign launch, winning debate, and the historic nature of her candidacy, seems to have escaped Biden’s gravitational pull. According to a recent New York Times/Siena poll, Harris has a two-point edge as the candidate who “represents change.” Trump and his allies, struggling to weigh her down with Biden’s baggage, have spent $38 million on TV ads highlighting a comment that Harris made more than 14 months ago: “Bidenomics is working.”
