Introduction

With just days remaining before the election, new CNN polling reveals Democrats holding narrow leads in two critical Senate contests. The results underscore how competitive the upper chamber battle has become, even in states that leaned heavily toward one party in 2024.

What Happened

CNN/SSRS surveys released Thursday show Democrat Adam Hamilton leading incumbent Republican Senator Roger Marshall by four points in Kansas, 49 percent to 45 percent, among likely voters. In Maine, Democrat Troy Jackson holds a similar 4-point advantage over Senator Susan Collins, 49 percent to 45 percent, a margin that has widened slightly since August. Both leads fall within the poll's 4.5-point margin of error.

Why This Matters

The tight margins in Kansas and Maine highlight how the fight for Senate control remains fluid in the final stretch. Despite former President Trump carrying Kansas by 16 points last year, the race has become competitive, as have Democrat-backed challenges against incumbents in states that recently voted blue. Voter sentiment on cost of living and candidate favorability is shaping the outcomes, while both parties pour millions into final-day advertising.

Key Takeaways

  • Hamilton leads Marshall by 4 points in Kansas, with voters viewing him more favorably than his opponent.
  • Jackson holds a 4-point edge over Collins in Maine, with enthusiasm for Jackson lower among backers; many are voting against Collins rather than for him.
  • Both races fall within the 4.5-point margin of error, making the outcomes highly uncertain.
  • Cost of living ranks as the top voter concern in Kansas, cited by 43 percent.
  • Decision Desk HQ gives Marshall a 58 percent chance and Jackson a 57 percent chance to win, both rated as toss-ups.
  • Democrats' path to a Senate majority has opened up as competitive polling emerges in several red-state contests.

Conclusion

As Election Day approaches, the Kansas and Maine Senate races illustrate how quickly the political landscape can shift in the final days. With narrow leads, significant spending, and voter sentiment still in flux, both contests remain among the most closely watched in the 2026 midterms.
