We tracked the undecided races of the 2024 election

At about 4:30 p.m. Wednesday, Harris delivered remarks in front of supporters gathered at Howard University. She said it was important for those who supported her and voted for her to accept the results of the election, but not to give up the fight. She called for supporters to mobilize and organize to support democracy, the rule of law and reproductive rights and other freedoms.

Delayed for today is a reckoning with reported lower Democratic turnout in key swing states and the unconventional process that led to Harris advancing to the top of the ticket after Biden's decision to run for a second term. Of course, many factors led to Trump's win, but overall its clear that voters around the country were familiar with him and his campaign promises and voted for him despite the unfavorable opinion voters have of him, concerns they may have had with regard to the events of January 6, and the fact that he is the first president-elect with felony convictions and other indictments.

Harris's speech comes at a time when Democrats are thinking about the fact that not only is Trump is poised to return to the presidency, but that he will at least do so with a Republican majority in the Senate, and possibly the House.

Harris warned her supporters, "do not dispair," ending on a hopeful note by calling on Americans to "fill the sky with the light of a brilliant billion stars — the light of optimism, of faith, of truth and of service ... And may that work guide us even in the face of setbacks toward the extraordinary promise of the United States of America."

For more updates, our ABC News colleagues are continuing to cover the latest from the presidential campaigns on our Election Day live blog.

ABC News is projecting that Democrat Elissa Stotkin will win Michigan's U.S. Senate race, which was left vacant by the retirement of Sen. Debbie Stabenow. With 97% of the expected vote reporting, she has 49% to Republican Mike Rogers's 48%. Republicans had hoped to pick this Senate seat up and made it a very close race.

The contest to succeed the late Democratic Rep. Bill Pascrell in New Jersey's 9th Congressional District remains a close contest, though Democrats currently have a slight advantage. With 79% of the expected vote in, Democratic state Senator Nellie Pou currently leads Republican Billy Prempeh by five percentage points, 51% to 46%. While ABC News has not yet projected a winner in this race, the Associated Press previously called the race for Pou.

No matter how big the eventual margin may be for Democrats, Prempeh so far has refused to concede. Right now, he's currently trailing Pou by roughly 11,000 votes — a closer-than-expected result in a longtime Democratic district with a partisan lean of D+17.

In a recent interview with CBS News, Prempeh suggested that he could eke out a win. But he's falsely claimed that there are 67,000 votes left uncounted despite reports from Bergen and Passaic Counties that indicate that only around 2,000 mail ballots have not been processed. Pou, meanwhile, has already declared victory, noting that a win would make her the first Latina ever elected to Congress from New Jersey.

Working off our expected vote estimates can be a tricky business sometimes. We said earlier that there could be more than 100,000 votes left in Philadelphia. However, looking at data from the Philadelphia City Commissioners, the number of outstanding votes appears likely to be much smaller because only 16 remaining election divisions still have to report out 1,703. Obviously, if there aren't that many votes left in Philadelphia, then Republican Dave McCormick is well-positioned to maintain his lead and win Pennsylvania's Senate race over Democratic Sen.
