What to Expect on the Convention’s Last Night

The Democratic National Convention will conclude Thursday night with what is, by any measure, the marquee event of the week: when Vice President Kamala Harris takes the stage to formally accept her party’s nomination to be president.

The acceptance speech is historically a high-profile (and high-stakes) moment that provides candidates an opportunity to speak directly to the nation and offer a vision for their presidency. That’s particularly so this time.

It has been barely a month since President Biden dropped out of the race and Ms. Harris began her own campaign. She is still something of a mystery to these delegates, who are eager to see how — in tone and substance — she intends to take the fight to Donald J. Trump.
