US states grouped into clusters based on electoral margins in US Senate elections since 1954 (just before AK and HI were admitted). Clusters generated via a greedy modularity algorithm, split across the three senate election classes

TIL that the prehistoric Lake Agassiz (roughly the red outline) had five different outlets to the ocean at different period of time. (Please read the body)

  1. the Mississippi River via the Minnesota River,
  2. the Mississippi River via the St. Croix River,
  3. via the Great Lakes to the St. Lawrence lowlands to the Atlantic,
  4. via the Lake Ojibway to the Ottawa river to the St. Lawrence lowlands,
  5. the Hudson Bay

Network community map of the two most similar US states in presidential voting from 1912 to 2024, created by greedy modularity algorithm (please read the description)

Each state is connected to its two closest matches based on the average difference in presidential margins across elections from 1912 to 2024. Node size shows how often a state is selected as another state’s top two match; thicker/darker lines indicate reciprocal top two matches. Groups are created by greedy modularity maximization algorithm. Node position and physical distance have no quantitative meaning
