What was the damn point of the shutdown? People missed paychecks, families went without SNAP, and Democrats walked away with nothing.
This isn’t about moderates versus the far left. It’s about who’s actually fighting for people who are struggling.
She nails where so many of us are right now.

BREAKING
The 1st Circuit REJECTS Trump DOJ's request to pause a judge's order to pay up Nov's SNAP funds to the states.
The SCOTUS stay will expire within 48 hours absent further action from the justices, per its terms.

Suganuma et al provide a thorough examination of the Holocene collapse of the Lützow-Holm Bay ice shelf in Antarctica. They pinpoint when the collapse happened by investigating the beryllium isotopes. When the bay became open ocean, cosmogenic ¹⁰Be could reach the sediments. doi.org/10.1038/s415...
