Updating Data

To update data, modify the ELECTIONS variable in scripts/scrape_results_metadata.py with the ID from the Board of Election Commissioners website, and then regenerate input/results-metadata.json and output/results-metadata.json. Then re-run make all, forcing execution if necessary.

Once this is done, make build-output can be run to GZIP all files in a separate directory that can be deployed to cloud storage with make deploy.

To update the displayed elections on the site, update ELECTION_ORDER in site/_data/site.js.
