Asking someone which presidential candidate they’re voting for is about as socially taboo as asking a woman her age. But thanks to the Internet, you don’t actually have to ask any questions in order to get your answer. All political contributions are public information and you can easily find it on the web. Sure, you can’t be totally certain that just because your dentist gave the Clinton campaign $500 that means he’ll be voting for her–but it’s probably pretty safe to assume it. You can search contributors by geographic location, party affiliation, or name. So whether you want to know if your favorite actor is supporting the same candidate as you–or whether you want to know if you had your neighbor rightfully pegged–the answer is right at your fingertips.
