If you are part of an org in the US (PSL, DSA, FRSO et al), I think this is just the sort of thing you should be helping to organize for in your community.
Are any of you part of orgs or know orgs that are doing this work? If so can you mention them here?
as other posts are indicating, and from what i have seen personally, the orgs addressing this materially are community/municipal/state based. as i understand, SNAP is federally funded but administered by state agencies. so states with the political will and some cash can theoretically make their own contributions in the meantime, with the intention of recovering those funds when the shutdown ends. that kind of shit happens all the time, because a lot of federal projects are basically agreements where states spend their own money up front and then draw down federal award funds afterward. we are talking about big sums of money, but if all they need to do is float a month, that could pencil out in some states. however, it does mean that austerity-focused states, or states where the leadership doesn’t give a fuck about the working poor, are likely to fuck their people over in the short term.
the only thing i have even heard of going on at the national level is some lawsuit/court-injunction from a group of governors (~25) suing the USDA for failing to follow some rule regarding available emergency funds not being tapped for SNAP. i didn’t look too deep into it, because i’m not a lawyer and the courts are whatever. like i’m not shitting on the idea, it’s just not in my wheelhouse nor do i have anything to contribute to that effort. like i’m not gonna file an amicus brief or some shit.
