Over the years I developed the impression that Google was left leaning. I am currently researching the presidential candidates, specifically Michelle Bachman using Google for this example. I have heard that Michelle was being hit hard by the left. Not as hard as Sarah Palin. In “Googling” Bachmann I find I have to go 3, sometime 4 screens deep to find sites that I am comfortable with the thought that they might be unbiased. I know the internet search sites use a formula to prioritize presentation of the search results, usually by number of visits. I find it difficult to believe that there are so many more liberal researchers than conservatives on the internet.
With the current political climate I expected more artillery fire from the left at the conservative candidates. The results I am getting from Google convince me that there is a custom search algorithm for conservatives/Republicans in the Google search. When I go to Yahoo search I get a mixed bag of search results on the first page. I am not suggesting that you drop Google for Yahoo. I am saying you will have to look hard to find unbiased political search results on Google. And it will get worse as the 2012 elections approach.
