The 2022 midterm elections produced modest, but perhaps still significant, changes to Congress. Democrats outperformed in many parts of the country, significantly stemming the tide of the “red wave” many analysts were expecting.

The results for partisan control of Congress remain in doubt.

The power balance in the U.S. Senate may not be known until next month, but the Democrats are seemingly poised to retain control. The Pennsylvania Senate seat flipped to the Democrats while Nevada could flip Republican with the Democratic incumbent currently behind. Three other Senate contests remain uncalled, with the incumbent party narrowly positioned to win all three. That would leave the Senate tied, waiting for the results of a Georgia run-off in December to determine which party controls the Senate.

The House of Representatives appears likely to shift to Republican control, but by the slimmest of margins. The final outcome and margins in the House will not be known until more votes are counted and several very close races are called. If Republicans win control of the House, as seems likely, it is unclear if their razor-thin majority—which could be between two and twelve seats—will allow their leaders to govern effectively.

To help assess the 2022 midterm election, we have prepared a comprehensive guide that summarizes the results and their impact on the 118th Congress, which convenes in January. The Election Guide lists all new members elected to Congress, updates the congressional delegations for each state, and provides a starting point for analyzing the coming changes to House and Senate committees, including potential new chairs and ranking members.

Our committee analysis assumes that the Democrats retain control in the Senate, but Republicans flip the House and chair committees.
