That merely sets the table for a quite limited experiment:
Websearch 1.
Websearch 2.
One explanation is that for those who write, and read, forming judgments apart from 30 sec soundbite mudslinging political commercials during the football games, there might be an overwhelming predominance one way, which a proper search algorithm would not ignore.
Readers can infer other things, if they want. Readers should independently on their own workstations repeat the two searches. It is not infeasible that Google search algorithms are keyed to Google collecting user data and tailoring returns to the profile as well as the query - just as they do for tons of money with targeted advertising.
Tell'em what they want to hear is not a new thing generated anew by the web, without any precedent.
