Looking at all available precincts in Hudson County, Sherrill support is higher in the most-densely Hispanic turf & tracks closely with '21. Turnout is *higher* than '21 across the county-- and even more so in the most Hispanic precincts.

The analysis you've been waiting for: "Do you remember who was actually president when that happened?" Turns out the answer is often...no.

1 in 3 forgot Trump was in office on Jan. 6.

HALF didn't say Biden was President during the Afghanistan withdrawal!

IR images extend about 600 km from the center of the storm to illustrate its shape evolution.

I jump into the moderation debate. I agree with @adambonica.bsky.social and @gelliottmorris.com on the methodology, but I want to draw attention to a bigger issue. The collapse of candidate effects generally.

Even after weighting, there's a ton of poll-to-poll variation in estimates of support within demographic subgroups. Saving this for the next time someone goes sub-group diving with future polls.
