In the USA count Mississippi, the Democrat won by a margin of only 5,000 votes, now they have 55 votes in the Senate. Only Alaska remains. That doesn't change the general situation, although in the Senate every vote could be important if a political crisis starts and Democrats need to get votes to override the veto on some key bills.
This is one of those red states where, even though the Republicans might lose, the probability of that was only a few percent. In 2024, Trump won 62% of the vote here, and Harris only 36%; The candidate for the Senate that year defeated his opponent by almost the same score: 62% to 37%.
