Whether there was widespread voter fraud or not, I see this election as rigged, largely by the media. There are dozens, more likely hundreds, of little incidents like the following that were thrown out there to influence the election. In this case, liberals viewing Google's home page saw a reminder to go vote, whereas conservatives received no such reminder. The practice stopped after the New York Post printed a story about it.
Google has also been accused of burying search results favorable to Trump and harmful to Biden. This is just one example of the unfair practices used by the media to help install Biden as president. And we all saw how the MSM relentlessly insisted unflattering lies about Trump were the truth, like the "very fine people" lie.
