A change of season in the American race

On 22 August, Kamala Harris accepted the Democratic nomination for president in a speech that closed four days of celebration in Chicago, and the arena that rose to greet her was doing something more than applauding a candidate; it was releasing a tension that the party had carried since the debate in June. The convention that the Democrats had planned as a victory lap for Joe Biden became, after his withdrawal, a remarkably swift reconstruction around his vice-president, and the speed of the change said as much about the party’s discipline as about the candidate’s appeal: the same organisation that had spent a year insisting that Biden was its man spent a month convincing the country that Harris had always been the future.

The novelty of her candidacy is real and worth naming plainly. She is the first African-American woman, the first South Asian woman, and only the second woman in American history to lead a major-party ticket, and the convention was visibly structured around the meaning of that fact, from the roll call to the speeches of the women who preceded her to the delegation from her mother’s country, India, waving flags in the aisles. The spectacle was careful, and the care was the politics: the party is betting that a coalition of the young, the non-white and the suburban, assembled around the relief of replacing a candidate voters had tired of, is a majority, and the week in Chicago was the first test of that arithmetic under full light.

Her speech itself was a study in the discipline that her campaign has adopted. She ran through the biography that the party wants the country to know, the prosecutor, the stepmother, the daughter of immigrants, the Black girl whose mother told her not to complain about being first; she sketched an economic agenda of housing, child care and the middle class; and she trained her fire on Donald Trump with the precision of a courtroom cross-examination, mocking his legal troubles and his obsession with crowds, and closing with the line that the party has chosen as its slogan, that America does not have to go back. The speech was delivered as an argument, not a sermon, and the difference matters: the campaign is treating this election as a choice between a prosecutor and a defendant, and the entire convention was arranged to make the contrast legible.

The polls that followed the reshuffle show a race that has narrowed to the margin of error, and the enthusiasm gap that was the Democratic problem of July has, for now, become a crowd problem on the Republican side. Whether the shift holds is another matter. The novelty that animates her coalition is also its fragility: the voters who are energised by the historic nature of the ticket may drift when the campaign becomes routine, the swing states that Harris is courting are the same states where Trump’s coalition is dug in deepest, and the two months of autumn will test a candidacy that has yet to be scrutinised under the pressure of a real campaign.

What the week in Chicago proved, at minimum, is that the Democratic Party can still change its mind fast enough to save itself, and that a ticket put together in a month is capable of filling a stadium. Whether it can fill a ballot box is the question that neither convention can answer, and the season that begins now, the autumn of a race that was supposed to have been decided in June, will provide the evidence. The summer belonged to the change; the autumn belongs to the test.
