Seems like a lot of this data is sourced from OpenElections[0][1]? Not sure about what makes this better than OpenElection's data, especially considering OpenElections seems to have done a large portion of the difficult wrangling work...
There should definitely be better attribution for this data.
A portion of it was sourced from openelections, yes. These were attributed in the PRs, but not in the README for the repository. We've corrected this oversight in attribution and issued an apology.
"A lot" of the data wasn't sourced from Open Elections. Derek's claim is not true. As far as I know one user used Open Elections data for a portion of their total contributions (and attributed it in their PR).
"Many" of the contributors (myself included) used primary sources for their data.
The one contributor that used OE data cited it and it was a small portion of their overall contributions.
There should definitely be better attribution for this data.
