Cook Shifts Two Senate Races To Toss Up: Midterm Red Flag
The Cook Political Report moved the Texas and Iowa Senate races to Toss Up on August 20, pulling two contests in states Trump carried by double digits toward the Democrats. The shift puts control of the Senate itself in play and names the causes: a damaged Republican nominee in Texas and an affordability backlash sharpened by the Iran war.
What changed
Four ratings moved left. Cook shifted Texas Senate and Iowa Senate from Lean Republican to Toss Up, downgraded Texas governor from Solid Republican to Likely Republican, and moved Iowa governor from Toss Up to Lean Democrat. All four moves ran in the Democrats’ direction.
The map math is the story. Both Senate seats sit in states Trump won by more than 13 points in 2024. When Lean Republican seats in Trump-plus-13 states become toss-ups, the party’s Senate majority is no longer a given.
These primaries are settled. These are not hypothetical matchups. Both states have chosen nominees, so the ratings reflect real candidates rather than open fields.
The matchups
- Texas: Talarico versus Paxton. Democratic Rep. James Talarico faces Republican Attorney General Ken Paxton, who won the nomination by defeating incumbent Senator John Cornyn in a May runoff. Cook’s downgrade rests largely on Paxton, calling him “deeply flawed” and “underwater by as much as double digits in some surveys,” and “notably underperforming even a generic Republican in GOP polling.”
- Iowa: Turek versus Hinson. Democratic Rep. Josh Turek faces Republican Rep. Ashley Hinson for the open seat that retiring Senator Joni Ernst is vacating. Two sitting House members, one open seat, now rated a coin flip.
Follow the money, and the fuel
Cook’s rationale identifies economics as the second engine, the one with national reach.
Affordability is the through-line. The report cited voters, “particularly in agriculture-heavy states,” who “may not soon forget skyrocketing gas prices, along with rising diesel and fertilizer costs.” Iowa’s farm economy runs on diesel and fertilizer, both of which have climbed.
The Iran war is the accelerant. Cook tied the persistence of high energy costs to the conflict, warning the pain could linger “even if the war in Iran were to be resolved and the Strait of Hormuz permanently reopened.” The foreign crisis is showing up at the pump and the co-op.
Candidate quality still governs Texas. In Texas, the driver is Paxton, not fuel prices. A weak nominee in a red state is the classic way for a safe seat to become a live one, and Cook is betting that the primary has handed Democrats an opening.
Why it matters
Ratings changes are not votes, but they move money and attention, and this one reframes the 2026 Senate fight. A cycle that looked like Republicans defending friendly terrain now includes two red-state seats rated even, which changes where both parties spend and how national donors weigh the map. The combination Cook identifies, a flawed nominee plus an affordability squeeze traceable to a foreign war, is the kind of pairing that turns structural advantage into a fair fight.
Worth watching
The variables are a Republican Party that still nominates candidates like Paxton and an energy-price picture tied to a conflict that Washington does not fully control. Cook’s own hedge is the tell: it warned that cost pressures may outlast the war itself, meaning the political damage could persist even if the Strait reopens tomorrow. Whether these seats stay toss-ups depends less on the candidates’ ads than on the price of gas between now and November.
