Sorry, I was technically incorrect. But the pragmatism of: they were a member of X party during Y election is a very close proxy to 'how they voted' - moreover, the motivation of the app makers is still oriented towards the publishing of essentially private information i.e. voting orientation. Which is not helpful. I believe Americans are far less extreme than the pop culture news outlets (basically almost all cable news) would have us believe. If you check Pew polling there is actually wide consensus on a lot of issues which see partisan but are really not.
