They changed the format a week or two ago. Some things are harder to find. This may be my browser, but now I can't find a way of seeing the option to make the map color coded by partisanship or race, the option to do so used to be above the map. I also can't find a way to pull up President 2016 data when the default for that district's data is Composite 2012-2016. I used to be able to do this in states that have 2016 Pres. data. Anyone know?
It's all in the top right in settings. It's actually much better because you can see different colors between races. Looking at gwinnett county from 08 to 2018 governor is great.
