It's already widely known that Google employees support Barack Obama ahead of the clean cut Ms. Clinton for the Democratic party presidential nomination. Interestingly, the Yahoo brigade also favour Obama, whereas those at evil lovely Microsoft prefer Hillary. I wonder if there'll be some employee "re-education" at Yahoo when Microsoft eventually forces through the takeover.
Now I have discovered some tenuous compelling evidence that there may be some sort of strong-arm tactics at Google to force the will of the company on its employees. Whilst enjoying an informative Google Adsense Optimization Demo presentation, I found the following blatantly partisan anti Hillary subliminal messaging within a presentation slide. Click "Pick Colors that Complement Your Site" to skip straight to the offending slide.
Examining the highlighted Adsense examples on this slide we can see the rather obvious anti Hillary propoganda. "Hillary is a Liar" barks the ad title of one, "anti-hillary" ad text in another.

Associating poor old Hillary with the oft-disliked current Republican administration in this way is also highly amusing and obviously reflects the political opinions of the presentation author (and possibly Google?).
