I scraped the results from izbirkom.ru. They are free to use for any purpose. The results are here. The format is one JSON object per line.
You can see an example of working with the dataset here. I used the dataset to recreate graphs found elsewhere on the Internet, with varying levels of success.
If you find a bug, please let me know.
If you want to fetch the data by yourself, you can repeat the scrape:
cd scrapyproject
scrapy runspider -t lines gosduma7/spiders/myspider.py -o results.json
You will need python3 and scrapy.
Be considerate and scrape responsibly.
