Giving Google the benefit of the doubt, they may not desire to have any political videos listed in their Top Lists. Though I admit, we don’t know, and it could be purposeful to hide the truth.
Hillary Uncensored is in the Top Ten on the right hand side of the page.
If that was true, it never would have been listed in the first place. Nor would the other, lower-ranked versions of the video be permitted. What actually happened is that they waited until it reached the top of the list, then deleted it.
In answer to the idea that they don’t list political videos in the top 100, I notice that one of the “popular” videos currently listed is “Bush Family Are Nazis.”
