The Cook Political Report shifted four U.S. Senate races toward Democrats on April 13, reflecting what the nonpartisan forecaster called an “increasingly sour national environment for Republicans.”

The Cook Political Report, which provides analysis of elections and political trends, said that all four moves favored Democrats—the largest one-sided batch of Senate rating changes this cycle. But the GOP remains favored to hold the upper chamber heading into the 2026 midterms.
