Being from Minnesota, I find this very interesting.
The Democrats (DFL in MN) will howl a lot about it as it will result in Minnesota finally having some GOP electors. In 2016, the presidential voting may have given Trump 4 or 5 of the 8 districts.
Generally speaking I am not in favor of this state by state splitting of the EC voting. In fact, I would think it may be unconstitutional.

select: US Presidential Election Margins by County
If you do this you will fond the map with each county and the margin/% for Trump and Clinton
The map is mostly red and pink. Five counties are pale blue meaning 1-5% margin for Clinton.
I really believe MN would have 4 EC votes for Trump under this new proposed law.
