I made a repo to scrape vote data a while ago: https://github.com/VikParuchuri/political-positions https://github.com/VikParuchuri/political-positions . It's a bit rough, but if you run `scrapy crawl senate -o ../data/senate.json -t json` to scrape, then look in make_matrix.py, you can get a nice .csv. The sunlight foundation (http://sunlightfoundation.com/api/ http://sunlightfoundation.com/api/) also has some great APIs to get this data. You should also look at govtrack (https://www.govtrack.us/ https://www.govtrack.us/) and countable (https://www.countable.us/ https://www.countable.us/) -- one or both might do what you're looking for. Edit: Never mind on countable -- looks like they changed their focus.
