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.

I really wanted the plugin hybrid version, but it was like $30K more expensive than the internal combustion alternative. We don't drive much, so we spent the money on solar panels instead.

When you're eating meals with folks, order something you can eat with a fork, not your hands (e.g., not a cheeseburger). You'll be the center of attention/talking a lot, so it's easier to sneak in small bites that way.

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

Do additional COVID vaccines really help?
We've accumulated a lot of scientific evidence in the last few years.

I just spoke to a fantastic former student who had a job offer rescinded after the new H1-B $100,000 fee policy was announced. "We like you... just not that much." The impact that this will have on people's lives & harm that this will do to the US economy are both infuriating.
