As far as the "this won't help Trump carry MN" takes, lolwut?
Liberal city vs more conservative suburbs/rurals is one of the oldest political dynamics in the book (way older than Trump), and statewide elections (both primaries and the general) in Minnesota and other Midwestern states have often hinged on this "everybody else vs the Big, Bad City" type mob mentality.
Letting Minneapolis fester in its own squalor is going to serve voters in Minnetonka and Apple Valley just fine.
The money being denied to Minneapolis is not going directly to rural areas in MN (AFAIK) and the Republican party does still need some urban and suburban votes to win statewide. I'm not sure this will have much of a negative impact, but Trump's clashes with Whitmer and the ventilator drama in MI doesn't appear to have helped him and it seems to be snapping back harder than the other rust belt states.
