If presidential debates don’t really matter, as some have contended, Kamala Harris would not have been on the stage in Philadelphia on Tuesday night. Yes, the spectacle can lead to excessive focus on their impact. But Joe Biden’s disastrous performance, which triggered his withdrawal from the race, showed how these choreographed political events can catalyse, if not create, voters’ sentiment about candidates.
Only weeks before the nation makes its choice, Ms Harris’s success was critical. Debates are often remembered, as in Mr Biden’s case, when things go wrong. The vice-president didn’t merely clear the very low bar set by her boss – basic competence – but soared over it. Her desire to stick it to Donald Trump may not have elucidated matters for undecided voters who say they want to know more about her and her policies. She did mention a few, including measures to codify abortion rights and promote an “opportunity economy”, but was keener to focus on the broad messages.
However, Donald Trump thought the 2024 election would be about his supposed strength against Mr Biden. In contrast, it was Ms Harris who dominated the debate, from the moment she took the physical initiative by crossing the stage to shake his hand – dispelling uncomfortable memories of him looming behind Hillary Clinton in 2016 – to her remark that Vladimir Putin “would eat you for lunch”.
Mr Trump’s vanity made him incapable of resisting the obvious bait she laid out for him, especially her observation that supporters were so bored they were leaving rallies during his rambling, incoherent speeches. Her air of amused disdain for his lies gave her the air of, well, an experienced prosecutor listening to the desperate bluster of a felon. In hitting him on abortion, on healthcare, on democracy itself, she was clear and incisive. When he lied about Haitian immigrants eating people’s pets, she simply mocked him: “Talk about extreme.”
Mr Trump’s claim was symptomatic of his reliance on rightwing memes, while Ms Harris sought to reach across the aisle, touting her gun ownership and talking of an America where “we see in each other a friend”. He is still struggling to navigate a position on abortion that will maintain his evangelical support without alienating other voters, but on Tuesday he ludicrously claimed that Democrats wanted to “execute the baby”.
There was no doubt that this was the vice-president’s victory, albeit one facilitated by strong moderation. In a flash CNN poll, 63% of viewers said that Ms Harris had turned in the better performance, while 37% opted for her rival. Yet Ms Clinton was judged to outperform Mr Trump by a similar margin after their first debate in 2016 – and edged up less than 1% in the polls over the next week.
A boost for Ms Harris is desperately needed because polls suggest the candidates are effectively deadlocked, with Mr Trump gaining some ground recently after her initial surge. Inflation has softened to the lowest level since February 2021, and the Federal Reserve is preparing to cut interest rates. But improvements in the economic picture may not feed through to voting intentions quickly enough to help the Democrats. Cumulative disgruntlement at the cost of living is not quickly dispelled even when price rises slow and are offset by wage growth.
An extraordinarily turbulent race may yet have more surprises in store. Nonetheless, in a contest that comes down to a tiny fraction of the electorate, across a handful of battleground states, everything matters, be it debate success or – yes – Taylor Swift’s endorsement. Ms Harris’s campaign knew they needed a clear victory on Tuesday. But even as they celebrate, they know it is only one step along the way.
