It's well established that vote anonymity is an important part of representative democracy (discussed elsewhere on this site).
I was listening to 538 podcast today, and they were discussing phone polling and specifically, how different countries have different measured level of trust that people are willing to give when a person asks their political opinions and choices on the phone.
At which point, the idea occurred to me - someone can actually figure out who people voted for by using phone polling (either take a legitimate poll's individual level data dump - assuming they are dumb enough to store per-phone call data - or for the slightly more devious, take a phone directory that has names, call people pretending to be doing a legitimate poll, and instead simply record name, # and who they said they voted for/would vote for).
Question: did something like either of those 2 scenarios ever happen (that we know of?)
Related: Do any jurisdictions take steps to protect people's votes from being "outed" by the polls? . Please note that these aren't duplicates - one asks if this actually happened, the other asks if there are steps taken to prevent it from happening, whether it happened or not.
