How are the Polls Doing at Predicting Election Results?

UPDATE: The results have been updated to include the 3/15 primary results


People are always curious about how good of job the polls are doing at predicting election results. After the Democratic Primary in Michigan, I wanted to take a look at how well the polls are doing in each state. To visualize this I took the Real Clear Politics average and the actual election results in all the states that this data was available for. Below, you are able to find a couple visualizations that help to show the differences between the two.



The data for these visualizations come from the Real Clear Politics website. Excel was used to edit the data. Tableau was used to create the visualizations.

If the state has voted, and it is not listed, there were not enough polls conducted to create a RCP average.
