President-elect Donald Trump is the projected winner of all seven closely watched battleground states in the 2024 election, ABC News reports.

The final tally of swing state victories comes after Trump was projected to win Arizona -- the final state, overall, to have a projected winner after Tuesday's presidential election.

On the campaign trail, Trump and his Democratic rival, Vice President Kamala Harris, both made repeated visits to the seven battleground states.

Trump's sweep of the swing states netted him 93 total electoral votes.

His margin of victories in the swing states ranged from more than 189,000 votes in North Carolina to a much narrower 30,000 votes in Wisconsin, according to unofficial vote tallies.

With the projection for Arizona, the final electoral count for the 2024 election is 312 electoral votes for Trump and 226 for Harris.

That bests Trump's previous 304-227 showing in 2016 against Hillary Clinton and also tops President Joe Biden's 306-232 win over Trump in the 2020 election.

President-elect Donald Trump is the projected winner in Arizona, ABC News reports.

President-elect Donald Trump announced Saturday that two of his former cabinet members won't be returning with him to the White House.

"I will not be inviting former Ambassador Nikki Haley, or former Secretary of State Mike Pompeo, to join the Trump Administration," he said in a Truth Social post.

Trump thanked them for their service.

President-elect Donald Trump announced on Saturday that his close friend Steve Witkoff and former Georgia Sen. Kelly Loeffler will co-chair the Trump Vance Inaugural Committee, as ABC News reported yesterday.

"This will be the kick-off to my administration, which will deliver on bold promises to Make America Great Again. Together, we will celebrate this moment, steeped on history and tradition, and then get to work to achieve the most incredible future for our people, restoring strength, success, and common sense to the Oval Office," Trump said in a statement.

Witkoff and Loeffler have been among the biggest fundraisers for Trump this election cycle, hosting multiple key campaign fundraisers as well as accompanying him to campaign rallies.

On election night, information overload is almost unavoidable. With this in mind, 538 is here to offer you a guide for knowing whether a state might be in play as votes are tallied. We estimated county-level benchmarks for every state (save Alaska, which doesn't report votes by county) to offer a back-of-the-envelope gauge for how the election is going.

The benchmarks estimate what percentage of the vote Democrats or Republicans would need in each county for a statewide race to be roughly tied. That means if a candidate is performing consistently better than their party's benchmark as we get a meaningfully large number of returns (keeping in mind that the partisan split from early returns may shift significantly as the count continues), it's a decent sign that contender is on track to come out ahead in the final results. In the interactive, you can look for any state or county in the search bar above the map.

To explore how to use the benchmarks, let's take a look at one of the key swing states, Pennsylvania. On its state page, you'll find a county-level map and a table with benchmark figures, along with the share of the statewide vote that each county contributed in the 2020 presidential race. Above the map, you can toggle between the statewide races, choosing among president, Senate and governor (where applicable). And above the table, you can toggle between viewing benchmarks by margin (how much a candidate leads by) or by party vote share (what percentage of the vote each candidate has).

The map displays both the benchmark margin and the 2020 share of the vote from each county. The bluer a place, the more Democratic it would be in the case of a statewide result that's about tied, and vice versa for red and more Republican. And, the larger the bubble over a county, the more votes it contributed in the 2020 presidential election.

Take Philadelphia. Heavily Democratic, it contributed nearly 11% of Pennsylvania's statewide vote in 2020, so it's represented by a big, blue bubble. Based on our benchmark, we can expect the statewide result to be very close if Harris is leading in Philadelphia by about 62 percentage points (80% to 18%). If she's doing a bit better than that, it could signal that she's running ahead of where she needs to be in order to win; if she's doing a bit worse, it could be a sign that Trump has an edge in the state.

Of course, you should never rely on just one data point as determinative. Instead, you'll want to consider what the returns are saying across a large number of counties, and only once a large portion of the vote has come in from each of those places. Additionally, you might look at a place like Erie County in the state's northwest corner, which has a reputation for being one of the state's bellwethers. Tellingly, our benchmark there is basically a tie, so if one candidate is running a few points ahead, that is probably a good sign for them.

We hope these numbers prove to be a helpful shorthand for who might be leading in close races as the returns come in. And even in the uncompetitive states, they could provide a hopeful Republican a sense of what it would take for their party to carry California in this day and age, and a hopeful Democrat a clue as to what their party would need to compete in South Dakota!
