Midterm Election Digest

A new Emerson College poll (fielded Sept 15–16, published Sept 18) shows Democrat Adam Hamilton at 45% to Republican incumbent Roger Marshall's 43% — within the margin of error in a seat neither party has treated as competitive this cycle. Same survey has the governor's race at Masterson (R) 51%, Holscher (D) 44%. Both Cook and Sabato still rate the Senate seat Likely/Solid Republican; this is one poll, not a rating change.

A ReconMR/Siena University poll (released Sept 17) gave Democrat Gina Hinojosa her first outright lead of the cycle over Gov. Greg Abbott, 49–45%, built on a 65–27 edge among independents. A same-week Emerson poll still had Abbott up 49–46, and other recent surveys are mixed. Prediction markets have moved too: Kalshi and Polymarket both cut Abbott's implied win probability from 87% a month ago to 76% now. Cook and Sabato still rate the race Likely Republican.

Nate Silver's Deluxe forecast put Democrats' probability of winning Senate control at 65% as of the Sept 20 update — up from 59% on Sept 18 and, per the model, "the highest they've been this cycle." The move tracks a run of strong generic-ballot numbers: NYT/Siena at D+8, YouGov/Economist at D+12 among likely voters.

Across the 37 House districts Cook rates as competitive (median Trump+5 in 2024), a Cook/New River Strategies/GS Strategy Group poll (fielded Sept 8–11) found Democrats leading the generic ballot 49–47 — roughly a 7-point swing from those districts' 2024 baseline. Trump's approval within these specific battlegrounds sits at 42% favorable / 58% unfavorable. This is a poll of competitive turf, not a set of individual rating changes.

Cook's Senate and House rating pages remain dated Sept 15 and Sept 11 respectively — no additional move since the Iowa Senate shift reported in Friday's issue. Sabato's Crystal Ball has not posted a new weekly ratings piece since Sept 17's "Seven Weeks to Go" (already reflected in this digest's score log).

A federal judge (Mary Kay Lanthier) dismissed the Justice Department's suit demanding Vermont's full voter file — including home addresses, birthdates, and partial Social Security numbers — ruling the administration exceeded its authority; Vermont's Secretary of State had refused the request on privacy grounds. Per a University of Wisconsin Law School tracker, this is the 23rd of 31 state DOJ voter-data suits dismissed at the district-court level nationwide; no court, at any level, has yet ruled for the DOJ (one appellate court, the 6th Circuit, affirmed a dismissal in Michigan back in June).

The DHS v. League of Women Voters fight over the SAVE citizenship-check database remains before the Supreme Court with no ruling since it became fully briefed on Sept 15. The lower-court injunction blocking DHS from running bulk citizenship checks against state voter rolls stays in effect in the meantime.
