Obviously Biden wants to do this, but he’s signing on this specifically because in exchange he’s getting all the money he wants for Ukraine and Israel.

huh? if the GOP rejects the deal, Biden gets a feather in his cap, if the GOP rejects the deal, they look extreme and silly to the small sliver of marginal, contestable voters.

obviously there's nothing Biden can do to win MAGA chuds; they'll pick the real fascism every time. but he doesn't need to -- he only needs to cement the 3pct or whatever of normal suburban whites who used to be moderate Republicans (the same constituents that he took in 2020). and those people probably don't like the "vibe" of American being overrun by foreigners, and also probably think that seceding from the Union is unserious and dangerous.

also, I'd think: the material interests just won't produce a progressive, humane policy; the people that would most materially benefit are the prospective immigrants who are definitionally non-voters. the Atlantic readers with No Human is Illegal yard signs aren't abandoning Biden for this; the Left, such that is, has already been brought to heel (and those who plan to withhold votes or support are already jumping ship over Biden's genocide; in for a penny, in for a pound, the Dem advisors must think).
