Presidential Elections by State: 1980 to 2016
This visualization shows the difference between the
percentage of the vote for the two main parties.
Voter turnout was calculated as the total votes
cast divided by the voting eligible population in
that state. Washington D.C. skews very far to the left,
so it was omitted it from the graph.
This line graph shows the voting differential, and
also include the 1976 election, but have
no turnout statistics.
These final two line charts isolate some notable states, and
have Washington D.C. removed from consideration again.
This final plot shows all the elections in detail. It's main
purpose is to clarify any final questions that could not be
answered by the previous visualizations. Like the line graph,
it does not include turnout, but does include the 1976 election.
