For starters, there's the national popular vote interstate compact, which would remove the influence that district and state boundaries have over the presidential election.

Assuming all pending states enact the compact then there are only two electoral college votes remaining.
By making it so that these few purple states retain solid blue control, it help preempt this possible last pushback. that would go a long way to changing the landscape. All of a sudden it would finally sweep away all this conservative nonsense by clearly showing that it is not as popular of a position as it seems right now and the current democratic position becomes the base level conservative position. That will be the lasting legacy of this compact I so badly want to see in my lifetime.
My hunch is they need to push harder into turning PA solid blue. Maybe AZ long term? Or maybe Iowa. Maybe just pick off the small states like Iowa, NH and include PA and that should be enough votes to solify the compact.
