In this commentary, Dr Allison Evans examines the political dynamics surrounding the 2026 U.S. midterm elections, focusing on the balance of power in Congress and the factors shaping electoral competition. She discusses traditional midterm patterns, presidential approval, closely contested Senate races, and the broader implications of a possible change in congressional control. Particular attention is given to the uncertainty surrounding the Senate, where the limited number and geographic distribution of seats up for election make the outcome considerably harder to assess.

The commentary also offers a closer look at Nevada as a prominent “swing state”, illustrating how national political trends interact with local electoral dynamics. Drawing on congressional and gubernatorial races in the state, Dr Evans highlights the competitiveness of Nevada politics and the possibility of voters supporting candidates from different parties in different races. Overall, the piece provides a practical overview of the key factors to watch ahead of the 2026 midterms and explains why these elections may have significant consequences for the direction of U.S. domestic politics and governance.
