Well known people with a specific leaning sending an email to vote and search engines manipulating results are no different than newspapers, news channels and snail mail from the past that are biased. I could manipulate votes at Thanksgiving dinner with the family.
It's left to people educating themselves on the issues and fact which includes weeding through biased opinions. Unfortunately, we've become a society where many people believe everything they read in social media.
I watched some of the testimony on Wednesday. I don't know if Trump is guilty or not but everything I heard was hearsay passed through multiple biased parties and opinions. Nothing that would typically hold up in a normal court but just suggestions to help manipulate public opinion.
