Introduction
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.

Republican
Democratic
Note: Both Y Axes appear to be the same size, but they auto adjust. The Democratic results have a wider range then the Republican results.

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.
