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

Non-white voters are rapidly trending toward right wing parties in Canada, the UK, and potentially other countries as well as the US.

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!

@zohrankmamdani.bsky.social is a great example of how far you can go if you genuinely center your campaign in an engaging way around the issue that voters overwhelmingly say in surveys they care the most about

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.

Explicit antisemitic attitudes are now much more common among young voters - 18 year old registered voters are now ~5x more likely to say that they have an unfavorable view of the Jewish people than 65 year olds.

In Norway the gender gap in support for left wing parties among high-school aged teenagers *doubled in size* during covid, with the increase being mostly driven by a dramatic increase in the share of teenage boys who believe "gender equality has gone too far"
What might explain this? A strong candidate is views about gender equality, which have changed just as dramatically as political orientation in recent years. Boys increasingly believe that "gender equality has gone too far".
