Both seats will be Republican if the independent redistricting commission is truly nonpartisan
(Though full disclosure - without hindsight, before the new district numbers came out for 2021-2031, I was pretty sure MT was going to stay at one at-large seat, not gain a second one, so I would've then gone with option 3.)
Yes, it seems Republicans on this board think that every redistricting decision everywhere should always favor Republicans.
It's almost like this weird per-conceived notion that redistricting is intended to be a benefit for Republicans exclusively. It's really kinda strange.
TBF to make a D seat in MT, you kinda have to do a bit. I think a fair map is a lean R seat and safe R seat as that’s how most clean maps default.
