Was on HN but flagged. Google replies:
"Google Autocomplete does not favor any candidate or cause. Claims to the contrary simply misunderstand how Autocomplete works. Our Autocomplete algorithm will not show a predicted query that is offensive or disparaging when displayed in conjunction with a person’s name. More generally, our autocomplete predictions are produced based on a number of factors including the popularity of search terms."
Seems like "criminal" and "indictment" are filtered out, which happens to benefit Hillary but seems to apply to other people. I tried a indicted people and it didn't autocomplete.
