No, because this reduces our geographical disadvantage.
We should still campaign in these places and try our best to get as many votes as possible, but the current geography is awful for Dems. These new shifts aren’t a terrible thing if we can balance them out with other gains.
If anything we should prioritize doing better in Mid size cities/towns in smaller states such as Boise, SLC, and Anchorage where the city itself is large enough to determine the state.
Boise definitely isn’t large enough to determine the whole state. Dems could handily win Ada county but that won’t change the fact that Idaho is safe R.
