It's always manipulating the results....by design. Google will show you the links that it thinks the majority of people are looking for, based on your search term. It might even adjust them a bit if it knows more about you. So if I'm a minority candidate in an election, with a weak online campaign, there is a chance my content is filtered out simply because Google thinks I'm noise. Or I'm pushed several pages down in the listings. As a person using google, I can tweak my search to find better results, but only if I know the results are there to find." What color of lipstick does Trinity wear in the matrix" will get me a vastly different answer from "What color lipstick do movie stars wear?" Same for politics - "What candidate supports gun control" will get you a different result from "What candidate is looking to limit the caliber of rifles to .22". Both could get me a politician, but the first is going to get me a far more generic "popular" link then the much more specific second. And if I don't know I'm looking for the second guy, I might stop at the first.
