Cook Political Report rates all GOP-held 2026 Senate seats except Maine, North Carolina and Ohio as "solid Republican".

Judge against the Cook Political Report's 2026 Senate ratings in effect on 2025-05-12. Take every Senate seat held by Republicans that is up in 2026, including any special elections then scheduled. True: every such seat except Maine, North Carolina and Ohio is rated Solid Republican, and those three are rated something other than Solid R. Mostly true: the pattern holds except for one minor discrepancy, such as one additional seat rated Likely R, or one of the three named seats rated differently from what the claim implies. Mixed: two or three seats break the pattern. Mostly false: several additional GOP-held seats are rated below Solid R. False: the ratings differ substantially from the description.

1. E1 CPR In Brief -- Tuesday, August 19 The Cook Political Report · 19 August 2025 Own record

   “We are shifting our rating from Likely to Lean Republican.”

The only evidence, E1, is a Cook Political Report item from 2025-08-19 announcing a shift from Likely to Lean Republican. The quote does not name the race. It also dates from three months after the 2025-05-12 date the claim must be judged against. Nothing in the evidence shows how Cook rated the GOP-held 2026 Senate seats on 2025-05-12, so the claim cannot be judged under the criteria.
