The current Supreme Court has forfeited all legitimacy.

Democrats (and everyone) need to address that reality.

John Roberts > Roger Taney.

Court needs to expand. And have fixed termsβ€”like *every* other supreme court in developed world. And have ethics rules, like all normal organizations.

Picture of "The Price of Democracy." 

From the framing of the Constitution to the decades-long backlash to the civil rights movement, the battles most pivotal in defining our democracy have hinged on one issue: taxes. 

"Taxes are not just the lifeblood of government. They are the wellspring of democracy. That is the revelatory message of Vanessa Williamson's propulsive, panoramic history." --- Jacob Hacker. 

"I love this book... The Price of Democracy makes a convincing case that we must take back the power of taxation to restore our democracy." -- Heather Cox Richardson

Agree: change is that the "institutionalists" have stopped pretending

-Thomas/Alito: They're the equivalent of "Trump +35" safe House district

-Gorsuch (in Garland seat) equiv of "Trump +22"

-But Kav, ACB, and mainly pious 'just call balls and strikes' Roberts wanted to be seen as open to facts

Rubio defended the strike on Wednesday while visiting Mexico, arguing that the typical interdiction procedures that the U.S. Coast Guard conducts to arrest drug smugglers didn’t work in these cases.

β€œThese drug cartels, what they do is they know they’re going to lose 2% of their cargo,” Rubio said. β€œThey bake it into their economics. What will stop them is when you blow them up.”

The new USG explanation for directly targeting the shipwrecked is because they could've helped salvage some cocaine?

But recall:

Rubio said (on Sept 3) the objective was to kill the people, not to seize/eliminate cargo, because cartels had already priced in the loss of cargo.‡️

What happens when ChatGPT cites to a real case but misstates what the case stands for?

That doesn't fly for Judge Behm in Michigan.

The court says that while a litigant could make the same error based on faulty reasoning, LLMs can't, because they can't reason.

What happens when ChatGPT cites to a real case but misstates what the case stands for? That doesn't fly for Judge Behm in Michigan. The court says that while a litigant could make the same error based on faulty reasoning, LLMs can't, because they can't reason.

And while a litigant might get away with similar overstatements because they could, perhaps, reason their way to showing how a case's stated holding might extend to novel situations, an LLM does not reason in the way a litigant must. To put it in a slightly different way, LLMs do not perform the metacognitive processes that are necessary to comply with Rule 11.

When an LLM overstates a holding of a case, it is just piecing together a plausible-looking sentence

holy shit, an accurate legal critique of LLMs. LLMs don't reason because they're just stitching together plausible-looking sentences indifferent to the content

"Captain Gains" on Capitol Hill
Shang-Jin Wei & Yifan Zhou
WORKING PAPER 34524
DOI 10.3386/w34524
ISSUE DATE November 2025
Using transaction-level data on US congressional stock trades, we find that lawmakers who later ascend to leadership positions perform similarly to matched peers beforehand but outperform them by 47 percentage points annually after ascension. Leaders' superior performance arises through two mechanisms. The political influence channel is reflected in higher returns when their party controls the chamber, sales of stocks preceding regulatory actions, and purchase of stocks whose firms receiving more government contracts and favorable party support on bills. The corporate access channel is reflected in stock trades that predict subsequent corporate news and greater returns on donor-owned or home-state firms.
