🚨 🚨 A new Maine Senate general election poll from @ZenithPolls — on behalf of @MorePerfectUS — finds Susan Collins in a tough position in her bid for a sixth term. After voters read bios of both Dem candidates, Graham Platner outperforms Janet Mills by 6 pts. Let’s dive in 🧵

How demoralizing for our Asian American communities to be excluded again and again. If your pollster doesn’t prioritize you, it’s time to break up. We can do better. Eg. @ZenithPolls

Hi there! We provided an extraordinary amount of detail in how we obtained sample for this poll. Radical transparency, especially around sampling and models and weighting, is at the core of everything we do. Please see below, and the full deck here: https://t.co/hMLKO7ueqs
@jacobkornbluh Considering Zenith Research doesn't disclose their methods of obtaining a sample, this should be taken with a grain of salt.

Also in Zenith Research/Public Progress Solutions poll: Mamdani has 43% of the Jewish vote, including 67% among younger Jewish voters aged 18-44. Cuomo at 26%, and 33% among Conservative/Orthodox Jews. Adams at 15% with Jews, at 27% with Con/Ortho. (Sample 152 LV)

That tracks with the crosstabs of my and @amitsinghbagga’s recent poll, which had Mamdani leading with 35% of Jewish registered voters. Though always better to get a larger sample size just polling one population (n=800) than a standalone crosstab subgroup (n=186)!
New GQR poll of 800 Jewish New Yorkers has Mamdani leading with 37%. Commissioned by New York Solidarity Network, whose leadership campaigned against Mamdani. More results: https://t.co/4UPWrmDE3w

Fun fact: I played a small role in offering feedback for the framing and sampling of this poll. Special thanks to Adam for doing his due diligence to first call those of us who work with local communities on the ground.
🚨 🚨 A new NYC mayor general election poll from @ZenithPolls (me) & Public Progress (@amitsinghbagga) — the most comprehensive poll of the race — finds Mamdani with a commanding 28-point lead in a five-way race, and getting >50% head-to-head vs Cuomo Let’s dive in, shall we? 🧵

Our poll’s sample size wasn’t large enough to break out NYC Hindus by age (even though it’s the largest of the cycle thus far), but I wouldn’t be surprised if there was a stark generational difference among Hindus re: Mamdani, like we are seeing across nearly every other subgroup
While dangerous, lethal right-wing Hindu nationalism is the unequivocally dominant force in Indian politics, our (@admcrlsn) latest poll shows Zohran winning South Asians (within which Indians were largest sample size) by 75 points. No question there are haters here, but money

Here’s the full segment of me and @amitsinghbagga on Fox 5 that aired last night talking about our new, uniquely conducted poll of the New York City mayoral general election. Thank you so much to @morganfmckay for having us on!
If you’re in the NYC media market, check out @amitsinghbagga and me on Fox 5 (*not* Fox News) around 6:30pm ET talking about our poll of the New York City mayoral general election!!

I agree! It makes everyone smarter Pollsters can be very territorial re: their “secret sauce” / sensitive about criticism We’re all just doing our best to capture the moment accurately & inevitably fall flat sometimes But it’s critical to understand why so we can learn from it
I’d love to see other pollsters join in public post mortem discussions. There is a lot folks can learn by engaging in conversation with each other instead of consultants feeling like they need to have all the answers and discouraging questions about assumptions and methodologies.

A few things we plan on doing that we hope will set us apart: 1) For publicly released polls, full transparency on how we arrived at our assumptions for modeled electorates 2) For publicly released polls, conducting post-mortems after elections re: what we got right & wrong

6) Prioritizing respondent experience, ensuring answering polls are not too onerous for any demographic group 7) Pairing quantitative polls with qualitative focus groups to get a fuller picture of a particular race, issue, or topic — and releasing results to public when possible

4) Exploring new methodologies (e.g., interactive AI-based interfaces) to try to combat the ever-growing challenge of non-response 5) Conducting polls in multiple languages in areas where relevant, maximizing respondent comfort in answering in their preferred language
