Using the latest 2026 redistricting files, the data shows Republicans drew themselves ~9 new safe House seats. Democratic counter-maps in California and Utah claw back 6 — netting the GOP about +3. #EconSky

Interesting essay by @rbmyerson.bsky.social on reasons why political competition in the US has broken down, w/ implications & fixes.
Such strategic neglect and the resulting geographic polarization become dangerous when constitutional democracy itself is at risk. Neglected regions can become fertile ground for the divisive rhetoric of demagoguery. When large groups of voters believe that only one party is really paying attention to them, they may feel no real stake in our system of multiparty democratic competition, and so they may support their elected leader in shaking off democracy’s inconvenient constitutional constraints. With such mass support, an unprincipled president could subvert democracy while portraying his actions as democracy’s ultimate fulfillment.

Thus, the defense of democracy against an authoritarian challenge may require political priorities that are fundamentally different from the standard playbook for winning elections. When the goal is to defend democracy in America, it is vital to ensure that Americans everywhere can see the benefits of having two parties competing for their votes.

The acting CDC director has now approved ACIP recs allowing anyone 6 months+ to receive an updated Covid-19 shot after discussing w/ their provider. If you are on the fence about getting an updated shot, read my in-depth take on the evidence we've accumulated on these vaccines. #publichealth

Great read on invasive plants in forests around Chicago. TL;DR: they're out of control. 77% of forests have been overrun (see: map) & require constant maintenance.
"Researchers with Purdue University and The Morton Arboretum used LiDAR to map where invasive shrubs are located in the Chicago Region."

An amazing scoop by a 17yo high school journo. A long list of wealthy Trump fans donate to the Republican Party of Guam which then sends $ to RNC. This roundabout route is bc they already maxed out donation limit to RNC. Some advisor thought nobody would dig into Guam. But then came Zach Kahn.
