Tires cause up to 90% of road microplastics, with the average tire losing 6- 9 pounds of rubber in a lifetime. Just how bad is the toxicity?

Every single Minnesota news outlet should be shoving microphones into the faces of Demuth, Robbins, Lindell, everyone else running for governor, and every MNGOPer licking trumps ass to ask if they agree with this shit. It’s time we know.
Donald Trump is now reposting videos on Truth Social suggesting that Minnesota Governor Tim Walz had Melissa Hortman assassinated.
This is objectively evil, and calling it out should not be political.

You can introduce articles of impeachment at any time, Zoe.
You can also work to convince your Republican colleagues that illegal wars aren't good for their electoral prospects. Stop acting like you have no agency here.

Trump illegally attacked Venezuela without constitutionally required approval. Trump says it's to take their oil and that his cabinet members will run the country.
Will any Republican members of the Senate or House finally stand up for the Constitution? Have they no shame?

Starting a war without legal authority and abducting foreign leaders is a dangerous abuse of power. Congress needs to wake up before another generation of young Americans is sent to die in a fool's war over oil.

Not a single bike rack anywhere in sight, despite a huge surface parking lot. So once again, I have to resort to the St Paul special, this time locking directly to the gas line next to the downspout dripping all over. But apparently I'm supposed to be a sycophant and only say nice things.

I left fully in Jan 2025 — except the weekend of June 14th — and am never going back. When I left, I had close to 30,000 followers, so it wasn’t *easy*. But when people send me links to tweets and I’m back on Twitter for a minute, it’s so Nazi forward. I’m shocked anyone real is still there.
All electeds and state governments should get off Twitter

This has always been a Bluesky-first campaign. But as of today, we will no longer be using Twitter. At all.
And I'm calling on other candidates to follow suit.

For top paid Oakland city staff in 2024 you have to go 109 people deep before reaching someone who isn’t police or fire. That’s the City Administrator w a salary of $308k & total comp of $506k. They’re the only non police/fire staff staff w total comp >$500k.

There are so many elements in our culture where you have to cope with people who don't even understand their own prejudices. People hate cyclists and they haven't put any effort into thinking about why or how it makes them think or say very stupid shit.
