6 Things to Watch For at the Democratic Convention

The Democratic National Convention, which opens Monday in Chicago, will be a test for the party and its new standard-bearer, Vice President Kamala Harris, who has never been so center stage. The next few days should signal how Ms. Harris intends to define her candidacy, and will help determine whether the party can remain unified despite deep divisions over issues including the war in Gaza.

Here are six things to watch for this week.

Harris presents herself: Ms. Harris’s acceptance speech on Thursday offers her a chance to introduce herself to what will likely be, along with her debate or debates with Mr. Trump, one of the biggest audiences she will have before Election Day. Her challenge, Democrats say, is to balance loyalty to Mr. Biden and assuming control of her party.

Her speech is an opportunity to show the extent to which she intends to carve out her own political identity and demonstrate how a Harris presidency would be different from a Biden presidency. Not incidentally, it is also a test of whether the sitting vice president will present herself as the candidate of change or as the incumbent, running on the record of the past three years.

Party unity: Democrats are hoping for four days of party-building, well aware of the dissension-free convention staged by Mr. Trump and the Republican Party last month in Milwaukee. That might be tough.

The convention will be shadowed by demonstrations over the Biden administration’s strong support of Israel in the war in Gaza, a policy opposed by a sizable contingent of Democratic delegates. Protests on the streets could spill into the convention hall. Should that happen, Paul Begala, a Democratic consultant, said Ms. Harris would need to separate herself from “the fringe of her coalition.” He added: “This is important in terms of defining her as both strong and mainstream.”

A handoff from a Clinton: Hillary Clinton is set to speak on Monday night, and thoughts about what might have been will not be lost on anyone in the hall. In 2016, Mr. Trump defeated her in her bid to be the first female president, a loss that some Democrats argued was at least in part a sign of Americans’ unwillingness to elect a woman to the nation’s highest office.
