What Decision Desk HQ Does:
Collect, organize, and report election night results and provide election related data to media outlets, political organizations, and anyone interested in who votes and how they voted. We do this for every Governor, Senate, and House primary, special, and general election. That amounts to over 1,100 races in 2018 alone.
