Cook Political Report

The Cook Political Report is the primary non-partisan subscription service used by political operatives, journalists, and academics to assess the competitiveness of US congressional, Senate, and presidential races. Founded in 1984 by Charles Cook Jr., it rates the competitive status of every House district and Senate seat on a seven-point scale: SAFE, Likely, Lean, or Toss-up in each direction. When Cook moves a district, it shifts how campaigns allocate resources, how donors prioritise contributions, and how national committees decide where to invest. Sabato's Crystal Ball at the University of Virginia is the closest comparable service; the two frequently move concurrently, and confluence of the two is treated as a strong institutional signal.

Cook has been the most active rating-mover of the 2026 cycle. On 7 April 2026, Cook moved Pennsylvania's 8th District from Lean Republican to Toss-up and Ohio's 1st District to Lean Democrat, the first major moves after the Georgia 14th District special runoff confirmed tariff-driven Democratic momentum. On 13 April 2026, Cook shifted four Senate races toward Democrats, including moving North Carolina to Lean Democrat following Thom Tillis's retirement announcement, the most significant single-day Senate ratings move of the 2026 cycle.

In late April 2026, Cook moved five Virginia House districts toward Democrats, contingent on the voided redistricting referendum map. Those moves were reversed when the Supreme Court of Virginia struck down the redistricting amendment 4-3 on 8 May 2026, restoring the 2021 bipartisan commission maps. On 13 May 2026, Cook moved Missouri's 5th District from SAFE Democrat to SAFE Republican, reflecting the post-Callais redistricting impact. On 3 June 2026, Cook moved the Iowa Senate race from Likely Republican to Lean Republican, with Cook's Senate editor citing the Iran War's effect on fuel and fertiliser prices for Iowa farmers as the direct cause.

On 18 June 2026, Cook moved seven House seats toward Democrats, with no movement in the opposite direction: AL-02, MN-01, OH-07 and SC-01 shifted from SAFE to Likely Republican; IA-02, MI-04 and NC-11 moved from Likely to Lean Republican. NC-11 now sits one notch from Toss-up. Every shift ran in the same direction. The June House map is following the Senate map that Cook began moving in early June, and the cumulative 2026 shift pattern, across Senate and House, reflects both tariff-economy drag and the structural limits of Republican redistricting gains.

On 1 July 2026, Cook moved the Alaska Senate race from Lean Republican to Toss-up, citing the risk that a name-duplicate primary challenger, also called Dan Sullivan, could siphon a decisive few first-preference votes from incumbent Senator Dan Sullivan under Alaska's top-four ranked-choice system. It was Cook's first Toss-up call in that race this cycle and extended the string of one-directional ratings movement, Senate and House alike, into a fourth consecutive month.
