I've just updated the ATF Gun Traces page on the Gun Violence Data Hub with newly-released 2025 numbers. Lots of interesting stuff in there, give it a whirl datahub.thetrace.org/dataset/atf-...

Thanks to @boltsmag.org for answering my Q about the American Community Survey!

NEW: Trump wants to transform the 2030 census in ways that'd dramatically skew representation. So we asked you to send us your questions. And we invited an expert on the census, who just published a new book interviewing 100s of census workers, to answer you. I learned a ton reading her replies:

"Over the counter, we have more of an ability to see if this is a sketchy transaction and stop it ... If we skip the counter, that’s not going to happen." Great look into the response to big proposed changes at the ATF from @bychipbrownlee.com + Champe Barton www.thetrace.org/2026/10/atf-...

If you have the option, always use a drop box rather than USPS to mail in your ballot

Taniel@taniel.bsky.social

*so important*: if you’re voting by mail, assume the USPS will delay because it’s its policy. You can: —put it in drop box —go to counter to watch them postmark in front of you —if you’re dropping it in a mailbox, do it VERY EARLY.

"There Is No Place For Us" is one of the best works of nonfiction I've read in a long time — if you're considering reading it, this interview by @jcollins.bsky.social with author @briangoldstone.bsky.social is a good starting point

Jon Collins@jcollins.bsky.social

It was a huge honor to talk with @briangoldstone.bsky.social, author of the amazing and heartbreaking "There is No Place for Us." I have a little review tacked onto the top of our conversation, but it's a stunning work that exposes the suffering we tolerate among our fellow citizens. (1)

Never good when the execs are writing things like "Always knew it was super shady" and "I cannot begin to tell you all the red flags with these deals. Just doing what I’m told"
