GOP message discipline has crumbled. JD Vance says I know it’s bad but give us a chance to fix it. Thune gaslights: You’re really better off; I don’t know why you’re complaining. Trump et al say An increase in gas price is a small price to pay, and Americans agree, for Iran not having a nuke

Representative Eric Swalwell (D-CA) observed that Trump “has more plans for the ballroom he’s trying to build at the East Wing than anything he’s gonna do next in the Middle East.”

I should add that the NYT story is the kind of story that few news outlets could devote the time and effort to do right, involving combing through federal, state, and local campaign finance reports, FOIA requests and other data. Their scale matters for something like this. /End (for real this time)

Don’t let Fox get away with it this time. Spread the word. Fox & Friends Weekend replaced footage of Trump attending yesterday’s dignified transfer with a clip from 2025. They clearly didn’t want their audience to see him disrespecting fallen soldiers wearing a baseball cap. H/T: @BadFoxGraphics

G. Elliott Morris: Republicans could stop this at any time they wanted to. “All it would take ….is 16 Republicans in Congress voting with Dem[ocrat]s to defund ICE (or 23 to impeach and remove Trump—3 in House & 20 in Senate). That’s it. 23 Americans can vote for the public and end all of this.”

Yes, but it should give you pause that the approval rating in his first and second term are similar and he was *re-elected*. The implication that ppl wish to draw is that similar policies and approaches by a MAGA candidate will not be supported in the next election. Wrong! So misguided…

While there are many differences across each higher ed institution, I think it’s fair to say that many would characterize their past year w similar “unprecedented” challenges and their futures as extremely challenging and necessitating significant reprioritizing of spend. I wish it weren’t so.

Goodall’s passing hit me hard. A mighty force of her own, pushing humanity to be better. Public goods provision must feel hopeless to the individual - Goodall urges us to keep on. But Yeats captures the moment for me. I am hanging on to Goodall for direction and energy while the beast slouches on.

Instead of blubbering and mumbling about some GOP members and Mike Johnson, why is this Democrat not announcing, full-throated, that the GOP controls the House, the Senate, the Oval Office and the Judiciary- and the shutdown is their fault. End of soundbite. Democrats gotta mumble.

Critical part of the President's new $100,000 charge for H1-B visas: The Administration can also offer a $100,000 discount to any person, company, or industry that it wants. Replacing rules with arbitrary discretion. Want visas? You know who to call and who to flatter.

One of the most profound books pub’d during my college yrs was “Hitler's Willing Executioners”. What stayed w me is the documentation of how ordinary ppl through ordinary actions furthered terrible ends. But the opposite is also true: Ordinary ppl can play a small part adding up to lg scale good.

Re job numbers, Trump answered: "Well, we're going to have to see what the numbers, I don't know, they come out tomorrow. But the real numbers that I'm talking about are going to be whatever it is. But, uh, will be in a year from now … I think you’ll see job numbers that are absolutely incredible.”

This is a cool paper that suggests that AI agents can indeed be used for social science experiments, but that just using a chatbot isn't good enough, instead prompts developed based on social & game theory makes AI agent actions predictive of real human outcomes. benjaminmanning.io/files/optimi...

NYT can’t/won’t report whom they voted for in the presidential election. Whole article is about how important public broadcasting is to these communities. It took a quote from Mark Amode ALL the way at the bottom (after detailing Murkowski’s “brave” efforts to carve out funding). Just gross.
