Young voters are now 3x as likely to report having been estranged from their parents for an extended period of time than voters over the age of 65.
Parental estrangement is uncorrelated with partisanship and is concentrated among low-turnout independents.

Amazon/Microsoft/Google/Apple all have very high net favs, Nvidia is unknown, Tesla is unpopular, Meta is somewhere in between
"Big tech companies" in general underperform the average of specific tech companies and are narrowly underwater - but still much more popular than both political parties

The issue landscape has changed dramatically over the last year - Democrats successfully have simultaneously raised the salience and expanded our trust advantage on our best issue (healthcare) *and* dramatically improved our trust advantage on the cost of living and the economy

Zohran's relentless disciplined campaign was truly impressive - he brought every message/issue back to the cost of living and built a model for what bringing attention to a positive affordability message can look like

The mayor race on Tuesday saw massive turnout differentials - turnout in @zohrankmamdani.bsky.social’sbstrongest precincts was up ~30% while turnout in Cuomo’s best districts were ~ flat.
These are big differences - essentially two different elections that happened to fall on the same day.

Traditionally there's been a quant/qual split on ad length in Democratic politics, with [usually more moderate] quants pushing for shorter 15 second ads and [usually more progressive] qual folks pushing for 60 second ads.
Great to see @zohrankmamdani.bsky.social sided with the nerds!

Zohran raised a lot less money than you'd expect given his vote share and educated coalition - he barely outraised Lander!
His prioritization of persuasion over fundraising in his public facing communication was extremely unusual and more Democrats should follow his lead!

This, from David Shor, is what I've been saying for a while. A lot of post-election punditry has decided trans issues are a "luxury belief" but also the obsessive hatred of us across the right-wing is somehow not. It's a rich man's game, society's wealthiest scapegoating the wrong 1%

Excited to join @ezraklein to talk through what happened in 2024.
There's a turnout story this cycle, but not the one we're used to talking about. With less-engaged and less-likely voters becoming more Republican, a larger turnout meant a more GOP electorate.

The defining psychometric characteristics of leftist anti-Dems after you control for demographics/ideology are pretty anchored around wanting to rebel against authority and be different than the mainstream.

Looking at the Berlin election map, the transformation of Die Linke's results from 2009 to 2025 is clear: not just the evolution from East-German party to East/West coalition, but the inner/outer Berlin switch too.
