U.S. Senate voting data (1989-2013)

This is raw data from GovTrack showing every vote made by every U.S. Senator from 1989 through 2013.

Some Python code to read the data:

    import json

    vote_data_by_year = json.loads(open("congress-vote-data.json").read())

    for year in range(1989, 2014):
        vote_data_year = vote_data_by_year["year"][str(year)]

        # do something with the data
