Does Google allow itself to be used to tilt the political debate?

Dan Gainor has this discussion at Fox News:

When Rick Santorum essentially tied in Iowa, he gave his campaign new life. He also guaranteed America would finally learn just how disgusting, vile and despicable the left is in this country. And how major news outlets and one of the most well-known businesses in the world – Google – are complicit in trying to destroy Santorum because he opposes gay marriage.
Santorum is the victim of what Reuters partner The Wrap and many other organizations call a “Google problem.” That’s quite the understatement. He was attacked with a Google bomb from Dan Savage, a gay advocate and sex columnist who hates straight people who don’t agree with him. He also thinks they should be silenced, bullied and blackmailed. That’s exactly how he’s treated Santorum. . . .
