we could have wall to wall coverage of Trump's health. it could be the most important issue in the country right now, and not without decent reason. there could be wild speculation about his bruising and his public absences. there could be multiple front-page NYT stories.

So the lab just got our first price quote with the Trump Tariffs included. Turns out that an increase in the cost of a scientific instrument by 39% (the tariff rate for Switzerland as of Aug 7) is…a lot of money! 1/

HUGE FLIP: Democrat Catelin Drey wins deep-red state Senate seat in Iowa, breaking the GOP's supermajority.
Drey won by 11 points in a district Donald Trump carried by 11 points last year. It's another massive overperformance. The Iowa GOP should be very worried for the midterms.

We talk about it in our piece, but Catelin Drey ran on a very clear message: affordability and education. It's a message that works everywhere.
