I'll be looking at state legislative districts in some next posts.
In preparation, I've created an interactive map using data from the amazing folks at the Open Elections Project. Below, I present data for State House, State Senate, U.S. Congress, and President/Governor for each election from 2010 to 2016. The 2010 and 2012 elections used the previous boundaries based on the 2000 Census, the 2014 and 2016 elections used boundaries based on the 2010 Census, which were approved in 2012 and are currently under review. I'll be looking at state legislative races in future posts.
A full scale version of the map is available at http://jtannen.shinyapps.io/pa_state_elections .
