HJL:
Search with Google, the candidate “Scott Walker” and then use Duck Duck Go to search the same thing. When I did it, Google queued up 10 articles on him that were all negative. The Duck queued up 6 favorable articles with four negative articles. I’m not necessarily endorsing Mr. Walker, but he is a controversial figure, due to his anti-union measures, making him a good example of Google limiting not just what you see but what you should think. – RV
