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.
Since it'll result in a bigger strain on state funds, no.
Both of those cities voted heavily for Hillary btw.
