What Political Party has Occupied the Governor’s Office In Each State for the Last 25 Years?



A lot of people have a good grasp of what political party has controlled the presidency and the Congress over the last 25 years. Most people don’t have much of an idea about what is happening in state and local politics in other states.

The visualization below shows what party has controlled the governors office in each state since 1991. It also has links to the Wikipedia page with the whole list of governors in that state as well as the Wikipedia page for each governor.



To gather the data for this visualization I transcribed the data from Wikipedia. I did this in a by year fashion. I used the logic that I would use the governor that was in office for the majority of the year to code that year. In some cases, certain short term or temporary governors were left out, but party control was almost never exchanged in this instance.

After transcribing the data, Microsoft Excel and Tableau were used to create this visualization. If you have any questions go ahead and leave me a comment.
