When the map opens the Indiana state house districts are displayed with semi-transparent coloring showing the party affiliation of the person holding the seat (red=R, blue=D). The data for the map is hosted on a GIS server operated by the state. I am *assuming* the data is current.
To change the map so it shows the Indiana state senate districts:
Click the basemap button (Next to the “Menu” button)
Look under the “Overlay” heading (mobile users scroll down)
Click the house layers to turn them off
Click the senate “fill” layer and then the senate “boundary” layer.
Seemed like the kind of thing that might interest readers of this site.
