People have been suggesting for a few years now that Google makes it’s search engine results favor Democrat candidates and that could affect election results. Well now there’s research that indicates that’s what happened in 2018.
Epstein and AIBRT analyzed Google searches linked to three highly competitive southern California congressional races in which Democrats won, and found that Google's "clear democrat bias" may have flipped the seats away from Republican candidates. According to the study, at least 35,455 undecided voters within the three California districts may have been persuaded to vote Democrat due to the biased Google search results. ... Analysis of this data showed a clear pro-Democrat bias in election-related Google search results as compared to competing search engines. Users performing Google searches related to the three congressional races the study focused on were significantly more likely to see pro-Democrat stories and links at the top of their results.
