Final uncalled Senate race in Alaska still close. See live results - USA Today

With Democrat Scott Colom prevailing in Mississippi's U.S. Senate race, there's only one more Senate election remaining uncalled, and it's still neck-and-neck.

In Alaska, Democrat Mary Peltola is slightly leading incumbent Sen. Dan Sullivan for a Senate seat that will cap off midterm election results for the upper chamber.

Midterms brought a forceful shift in power on Capitol Hill, with Democrats widely riding a blue wave to shift power in Congress.

But the race in Alaska, which was always expected to take a while to call, will be the final say in how wide a margin Democrats will hold for President Donald Trump's final two years in office.

USA TODAY's latest tally as of Nov. 11 shows Peltola with 48.9% of the votes to Sullivan's 47.3%, with about 89.3% of ballots counted.

According to the latest data from Alaska's Division of Elections, as of Nov. 11, more than 251,000 ballots have been counted, with 401 of the state's 403 precincts reporting results.

The state has a ranked-choice voting system, which means a candidate must get more than 50% of the vote to win. If they don't, there are more rounds of counting. In this race, the ranked-choice tally wouldn't start until Nov. 18 under state law.
