I feel that with this map, yes it does show what parts of our country "hang with each other" and it is evident that these parts cross state lines. But isn't that the point of the state lines? So that you dont have any 1 certain group of people (whether they be similar related in religion, political affiliation, or ideology) living in the same place. This is why counties get redrawn now so that certain political people do not consistently hold a majority in the white house. It good that these state lines are drawn, so they we have a diversity of people representing individual states.
