Yes, this trend I saw was based off of her surprising support with "very liberals" who we thought as higher propensity in the model.

25,000 simulations in, this is what the model is saying. Due to Kat's apparent fervent support among people who identify as "very liberal," (MDW crosstabs) she receives a better vote share when fewer people show up and the highest propensity liberals. For context 75,000 showed up in 2024.

A whale (or a sharp for all we know) bought a ton of YES contracts on Kat today. Immediately, the market makers came back to a bid-ask of 19 at 30 (now much tighter with 20 at 25). However, Kalshi still showed 37% odds, IL9.org immediately recognized this and throttled the Kalshi last-price weight.

Yes, when I was originally trying to build a model I was gonna use data from the 2022 IL-1 race which was a quite similar

This district’s primaries have had maybe two competitive races since my grandparents were born… and none in my lifetime, or almost two of my lifetimes, for that matter.

Two people — Yates and Schakowsky, have represented this seat for 97.5% of the time since 1949.
(there was a small break in 63’)

I genuinely hope we get more, but I am doubtful of more than one more high-quality poll. Also, no one has any clue what this district will look like (from a turnout by precinct perspective) bc it’s been so horribly boring and uncompetitive.

I understand. #NJ11 markets were criminally overpriced, even on election night. However, the polling for this race has been Sh** other than the DFP poll that had crosstabs, but that was so long ago it’s not useful anymore.

Yeah, I mean this model could be applied to basically every house and Senate race or primary. I looked around and IL7 lacks PMs in general (eg. the quick search I made though a few sites didn’t yield any results:)

I could make a market on Manifold or suggest one on Kalshi too, wouldn’t be too hard.
