I don't understand how hard it could possibly be to add 2016 or at least 2012 election data into DRA.
Precincts (VTDs) in many states changed after the 2010 Census, so that would require loading all the shapefiles for precincts and matching them up with election data. Some states change precincts after each election cycle. It's a lot of work to keep up. The Atlas doesn't have that available for all states either.
Haven't multiple places (Decision Desk HQ) already mapped out the 2016 vote by precinct?
