Fifteen days from the election, the candidates are locked in a dead heat. Harris is narrowly maintaining her lead in the polls, with polling aggregator FiveThirtyEight putting the vice president 1.8 points ahead of her Republican rival, 48.2 percent to 46.4 percent.

Federal Election Commission filings Sunday showed Harris’s campaign raised more than three times what Trump’s did in September. But polls still show a close race.
