It’s not bias. I think Google’s image search algorithm isn’t all that good.
Microsoft’s live.com’s results are much better.

yeah, right.
It's apparent to me that whenever someone types "palin", Google's search engine appends the words "racist" & "hate" to it.
Take a look another look you’ll notice no pictures of Sarah Palin - all derogatory images - and all the pictures of Obama and his rallies nothing but positives.
I find this pretty incredible.
It's deliberate. They did the same thing to disappear all of the images of Obama's bogus birth certificate. One day you found thousands of images, the next day the headings for the images were there, but the images were random images having nothing to do with birth certificates... just like the random images on the Sarah Palin rallies pages.
Once is interesting, twice is coincidence, three times is enemy action.
