Zohran Mamdani’s Muted Climate Politics
The self-described “ecosocialist” ran an ultra-disciplined campaign for New York City mayor. Once he’s in office, the climate issue could become unavoidable.

The Seattle mayoral election will be a nailbiter for sure. Incumbent Bruce Harrell is currently up 62k votes to challenger Katie Wilson's nearly 54k.
But as is typical for Seattle and its mail-in ballot reporting (there is no in-person voting in WA state), that leaves a lot of uncertainty. [1/n]
