Here is Montana, the first of the triple digit states

https://davesredistricting.org/join/4db97353-6b28-482f-b092-9c1822270e22This map has, per 2016 President:
21 Safe Democratic districts
5 Competitive Clinton districts
4 competitive Trump districts
70 Safe Republican districts
Of course this is Montana so I imagine that many of the "Safe Republican" districts would not be that safe.
As I often do for the minority party, here are the location of the 26 Clinton districts:
8 in Missoula
6 in Bozeman
3 in Butte
3 in Helena
2 in Billings
1 in Whitefish
1 Native American district in Glacier County
1 Native American district in Big Horn County
1 Deer Lodge County district
The median districts are district 62 and district 52.
District 62 is a northwestern suburb of Bozeman and went 59-33 Trump.
District 52 is a western suburb of Great Falls and went 60-34 Trump.
These are both roughly 6 points to the right of Montana at large, so winning a majority would be very tough for Dems, even if MT is very elastic downballot
For the record, in 2018 Tester wins 47 districts and Maryland Matt wins 53.
