The Fox News Decision Desk predicted that Republicans will take back control of the Senate in 2025 once the 119th Congress is sworn in.

The Republican Party officially won enough Senate seats in the 2024 elections to take back the majority from the Democrats. Senate Majority Leader Chuck Schumer, D-N.Y., has led the Senate since 2021.

The Republicans had a significantly more favorable map in terms of which Senate seats were up for election this cycle than the Democrats.

The Republicans up for reelection were all in relatively safe states, and the party was all but assured of a win in West Virginia to replace outgoing Sen. Joe Manchin, IW.Va. With a victory in West Virginia and the retention of all incumbents up for re-election, the Republican Party would already be at 50 members.

The Democrats found themselves in a much more difficult position. They expected to lose Manchin’s seat and face a fierce battle for the Senate seat of outgoing Arizona independent Sen. Kyrsten Sinema.

At the same time, several incredibly vulnerable Democrats in the Senate happened to be up for re-election this cycle, including Montana’s Jon Tester and Ohio’s Sherrod Brown, in red voting states, and Wisconsin’s Tammy Baldwin, Nevada’s Jacky Rosen. and Bob Casey of Pennsylvania, in presidential battleground states.

As if that weren’t enough, the seat of retiring Sen. Debbie Stabenow, D-Mich., was also at high risk of turning red.

Democrats only had a 51-member majority over their Republican counterparts, who had a 49-person conference.

Given its many vulnerabilities, the party could not afford to lose virtually any electoral battle in the 2024 elections.

What made the 2024 election even more difficult for Democrats to hold onto the majority was the sharp decline in split-ticket votes. In several states, the race was most likely decided by the winner of the presidential race, as voters were expected to choose one party and vote for candidates in that column further down the ballot.

When Republicans vote for their new leader this month, they will also select the next person to control the Senate after Schumer. The new Republican leader will succeed Senate Minority Leader Mitch McConnell, R-Ky., the longest-serving party leader in Senate history.

The newly elected Republican senators will participate in a secret ballot.
