What does that metaphor actually look like, in the real world?

We have known what SNAP looks like, to the GOP, for a very long time.

1976 – Reagan Uses Racist Tropes to Describe Food Stamp Participants During Florida Rally

In a 1976 Fort Lauderdale rally, President Ronald Reagan used racially coded rhetoric to undermine Food Stamps, as he had done in many places in the South. Among other racist untruths, he described white people as workers struggling to afford hamburger meat on meager salaries, yet painted Food Stamp participants as “strapping young buck[s]” who buy luxury items, such as a T-bone steaks, on the taxpayer’s dime.

Racism, and resentment of the poor, tied together, to advance the narrative that able bodied people have no business collecting assistance from the government.

After all, the "JCs" need replacements, for all the Proles they have lost, to immigration enforcement theater. So, starve people into working more hours.

Do you believe that had the shutdown continued, the GOP would have relented and agreed to the ACA subsidy extension?

iirc, the ACA subsidy was killed in the BBB, months ago. This was the attempt to fix that, as now, is the "later" they were banking on when the BBB was passed. Now, the Dems caved again, to pass a CR, with hopes of fixing the ACA subsidy "later'.

The ACA subsidy is dead. Looks like the regime is making it clear, SNAP is the next target, beyond the constraints put on it in the BBB.
