Look. It would be great if there was one simple trick for winning elections. But 'just be more moderate' isn't it.

In fact, you can use the NYT's exact method to 'prove' a 'Progressive Advantage' of +1.4 pts.

This piece shows what's really going on: funded candidates do better than unfunded ones.
The New York Times’ “Moderation Advantage” Is a Statistical Illusion
After accounting for money and incumbency the supposed electoral bonus for moderate candidates vanishes entirely.

Striking parallel between Trump and Liz Truss in terms of the power of economics/markets to turn even one’s own partisans against you.

Trump isn’t losing any support over his performative cruelty towards immigrants, but is rapidly losing Republicans over economic policy, stock market, inflation etc

6) Just 25% of US adults say they expect their finances to look better in five years than today.

That’s lower even than at the nadir of the Great Recession.

To review what we from @washingtonpost.com are reporting out of the IRS today:

- Projected tax revenue this year is down 10% ($500 billion) as Trump's downsizing is emboldening tax cheats

- IRS is nearing an agreement with ICE to assist on mass deportations

Interesting example of different intuitions about effect sizes.

i feel like this is evidence for my view that people experience trump through a strong form of ironic detachment. they literally do not perceive him as real.

Another way of saying this is that Trump’s claims are so extreme that even judges appointed by Republicans agree

As we show in a forthcoming JOP paper, this is an important signal to higher courts about the undelying merits of the claims
1/🧵 Judges across ideological lines are ruling against Trump at strikingly similar rates (84% liberal, 86% centrist, 82% conservative). This isn't partisan opposition to Trump—it's the judiciary functioning as intended by cutting across partisan lines to uphold the Constitution.

Last year we encountered a strange glitch in one of our surveys…the word “yes” was being replaced with the word “forks” in response options. Read on to learn how we unraveled what was causing it, how we ensured it didn’t impact the data quality, and what to do if it happens to you!
How a glitch in an online survey replaced the word ‘yes’ with ‘forks’
Dating back to at least early 2023, a bizarre and alarming technical glitch started popping up in some organizations’ online surveys and forms.

I spent a lot of time in my book breaking down WHY this is happening — it’s *content meets community*

- A lot of people don’t want “politics” or “news”, they want to be entertained…comedy, culture

- They want to feel like they’re listening to someone relatable, who talks like them, is like them.

Looks like we're about to get new data about what happens to a modern economy when you dismantle the liberal democracy that enabled it.

But the cost seems too high, and we have examples already; Italy 1922, Germany 1933, France 1940, Chile 1973, or Hungary and Turkey in the 2010s.

The stock market is not the economy. The stock market is not the economy. The stock market is not the economy.

Nonetheless, holy shit.

What’s remarkable is that there’s hardly any real news driving this. It’s just investors belatedly realizing that Trump is who he is, and always was.

What he said about Social Security payments has been repeatedly debunked - so the question isn’t whether he’s lying about this, the question is why.

What is this a pretext for? He and the GOP have long shown interest in going after Social Security. What are they going to try?
