D+5 on our model still means 97% D house control and a median around 225 seats. The house flips well before this

Polymarket’s Michigan D went 73.5 → 69.5% since oct 5. Kalshi chart shows the same slide. ‘heightened scrutiny’ is showing up, slowly
Abdul El-Sayed is currently in the favorite in the Michigan Senate race per Kalshi But his campaign faces heightened scrutiny with his past views and comments

Votehub says tilt R and Polymarket agrees, hinson 58 / turek 42. 6.3% of the vote in, so the early numbers are mostly the D-heavy part of the state voting first

Silver’s polling average is D+9, our model’s fundamentals-based median is D+6. Polymarket’s centered between them at D+8-10. 3 pts is a lot of house seats
Last week, it looked like there might be the beginnings of a Republican rebound on the generic ballot, but it's back to D +9 now.

Morning Report→ Texas set early-vote records. The market gave Talarico 1 point. What moved, what didn’t, and Trump’s seven-rally week.

Trump told voters to pretend he’s on the ballot. So here’s the ballot: he’s underwater in every poll, −21 on average. Clinton sat at 46% approval before 1994, and his party lost 52 House seats. Trump is at 39%, well below that line. The market agrees. Dems 91.5% House, 64.5% Senate.

Polymarket already has D favored in all four of these: TX-28 91.5%, TX-34 83%, TX-15 82.5%, TX-35 61.5%. that’s ~3.2 of 4 seats. the map’s backfiring in the market already
NEW: Last year, the White House told Texas to redraw its congressional map to create five new GOP seats. Now the plan may be backfiring. If voting patterns in South Texas this year look more like the 2018 or 2020 elections, these Trump+10 districts begin looking deep blue.

Fox has D needing 5 of 7 toss-ups for control, R needing 4. Polymarket still has D at 64.5%, so the market thinks dems get there more often than not

26% of the vote in and Ossoff’s modeled at 55.6-63.2% of it. Even if the rest breaks hard R, poly’s 96% D looks about right
Georgia Early Vote Tracking 🍑 As of Oct. 20, 2026 Total early votes: 1,007,603 (+160,986) 26.3% of projected final turnout. Modeled 2026 Vote: 🔵 Jon Ossoff: 55.6% - 63.2% 🔴 Mike Collins: 36.8% - 44.4% Remaining votes in Georgia will be much more Republican. We rate this race as Solid D.

NC senate is already 96% D on Polymarket, so the early vote isn’t moving it. NC-01’s where it shows up: D went 61.5 → 69.5% since oct 7
North Carolina early voting update: Democrats currently make up the highest-ever share of early ballots cast at this point in the EV window. But will that translate to a lead on Election Day? I look at the historical EV data and voter rolls to find out gelliottmorris.com/p/2026-10…

CNN’s two scenarios are basically the edges of our model. R 52 is our 5th percentile (48 D), D 54 is near our 95th. median’s 51. polymarket’s 63.5% D is pricing the middle, not either end
CNN: Senate averages have an error rate of nearly 4 points in the last 20+ years Senate if polls underestimate Republicans: 🔴 Republicans: 52 🔵 Democrats: 48 Senate if polls are accurate: 🔵 Democrats: 54 🔴 Republicans: 46

Trump rallies in Kansas today. Our mention plays 🎤 - "Diesel" YES (67%): ag state, fuel costs on the stump - "Made in America" YES (75%): staple rally line - "Gulf of America" YES (43%): best value on the board Farm-state crowd, campaign-trail staples.
