During the Bush years, it was a meme to search for biggest idiot or something like that and it would return President Bush. It was a relic of an SEO project done by a group of people.

After Obama was elected, a few people noted that the search still worked and a few days later, it no longer returned President Obama or anything like what it did before.

This was all the example one needs to know that your search engine results are heavily manipulated.
