Google has changed its algorithm and the Spreading Santorum site is no longer on the first page of results, though the first result (after election tallies) is a link to the Urban Dictionary definition of Santorum.
To me, it looks like Google has tweaked their algorithm to favor more recently updated sites, and since the landing page for Spreading Santorum hasn’t been changed for years, it was downranked. Four of the 10 first page links that aren’t news or election results still link to a frothy mix site, so it’s not as if Google is censoring that meaning. My take is that this is no big deal, but I’m a supporter of Google changes that favor more recent sites, because I’m constantly using the Google feature that limits results to the last year or month.
