Cook调整美选评级，预测市场反映德州爱荷华州参议员选情胶着

Texas and Iowa are becoming central to the 2026 argument over whether Democrats can genuinely expand the Senate map or are simply benefiting from a burst of early-cycle polling.

Cook Political Report’s latest update puts both states’ Senate races in the Toss Up column, while moving Iowa’s governor race to Lean Democratic and Texas’ governor race from Solid Republican to Likely Republican.

The shift matters because neither state was supposed to be this competitive. Texas was supposed to be a GOP Senate hold, even after Ken Paxton ousted Sen. John Cornyn in the primary. Iowa was supposed to lean Republican at the federal level, even with Republican Sen. Joni Ernst retiring and Democratic state auditor Rob Sand building a strong campaign for governor.

Now the rating map says Democrats have real opportunities in both places. Prediction markets say something more complicated.

Texas Senate becomes a real coin flip

The Texas Senate market is essentially dead even. It is also one of the most active state-level contracts in the country.

Kalshi has Paxton at 52% to State. Rep. James Talarico’s 48%, with $9.4 million in volume.

Polymarket has flipped the edge, giving Talarico 52% on roughly $866,000. That is exactly what a Toss Up looks like, two platforms looking at the same race and landing on opposite sides of the coin flip.

The polling is why Cook made the move. Talarico has led Paxton in multiple surveys, including a Texas Pulse/Texas A&M Bush School poll that put the Democrat ahead 47% to 43%, although that result remained within the poll’s margin of error.

Paxton’s nomination was always going to create a tougher general election environment than Cornyn’s would have. Republicans warned about that risk after President Donald Trump-backed Paxton won the primary, and the current market pricing suggests those concerns were not theoretical.

For Democrats, Texas is increasingly part of the actual Senate control plan, not just an exciting long shot. If they lose a tight race such as Michigan, a Talarico win would give them one of the few ways to replace it.

Iowa gets better for Democrats

Iowa’s two statewide races are moving in Democrats’ direction even more clearly.

Cook shifted the Senate race between Republican Rep. Ashley Hinson and Democrat Josh Turek from Lean Republican to Toss Up, while moving the governor’s race between Sand and Republican Zach Lahn from Toss Up to Lean Democratic.

The most recent Emerson College/Nexstar survey found Hinson leading Turek 48% to 45%, while Sand led Lahn by five points, 48% to 43%.

The contrast between the markets is revealing. Hinson remains ahead of Turek at 55% on Kalshi, where $1.8 million has traded, and 59% on Polymarket on $210,000.

But those are much smaller GOP edges than Iowa’s reputation as a reliably red state would normally produce.

Sand, on the other hand, is trading at 78% on Kalshi, with $465,000 in volume, and at 74% on Polymarket, with $71,000 in volume.

Traders are not merely accepting Cook’s Lean Democratic rating. They are pricing Sand as a clear favorite.

That reflects more than one poll. Sand has led Lahn in the New York Times/Siena, Fox News and Emerson surveys, and Cook cited both public and private polling to argue that the state auditor has opened a consistent advantage.

Sand’s 51% favorable rating also ran ahead of every other major statewide candidate in the Emerson poll, while independents broke heavily in his favor.

Abbott remains off traders’ radar

Texas’ governor race appears to be the exception in these races. Cook’s move from Solid Republican to Likely Republican is meaningful as a pundit signal, but it has barely changed traders’ underlying views.

Kalshi has Gov. Greg Abbott at 87% against Democratic state Rep. Gina Hinojosa on $692,000 in volume, while Polymarket has roughly the same pricing on only $58,000.

That is not a Toss Up trade. It is a market treating Abbott as a strong incumbent favorite whose race has become worth monitoring, not one whose position is truly in jeopardy.

Hinojosa is trying to make affordability her central case, including a proposal to send $1,500 checks to Texas households, but she still has to overcome a statewide Republican environment and an incumbent with deep resources.

For traders, the race remains less interesting than Paxton-Talarico. Abbott is not carrying the same general election baggage as Paxton, and he has not spent the year emerging from a brutal primary that exposed divisions within his own party.

The Texas Senate is a live national trade. Texas governor is a rating movement without a corresponding market panic.

The 2026 midterm Senate map

Cook’s moves add weight to the larger Democratic Senate path. North Carolina and Maine remain the party’s clearest pickup opportunities, while Michigan and Georgia are essentially required holds.

Ohio, Alaska, Texas and now Iowa offer additional routes to the four net gains Democrats need for a majority.

The catch is that none of these races is independently guaranteed. Markets still have Republicans ahead in Iowa’s Senate contest and narrowly ahead on Kalshi in Texas. But the direction of travel is unmistakable. What began as a narrow Democratic path has become a wider, more volatile board.

Ratings and markets are beginning to converge on the same broad trends. Democrats have put Iowa and Texas into play. They just disagree, at least for now, over whether the polling shift has gone far enough to make either state a Democratic favorite.
