Since cameras have become ubiquitous, stories like this - Governor Romney's comments before a group of contributors - don't even surprise us anymore.
Its interesting to consider what impact the inability to keep things secret has on politics, and how it alters the nature of governing. We just covered the Constitutional Convention and mentioned that it was done in secret. Since its often considered to have been a well crafted document, one wonders if such a thing might be possible today.
In a broader sense, cell phone cameras ought to be considered when we discuss the media, since they are effective ways to publicize information we might not otherwise get.
Update: BuzzFeed claims to know how the video got leaked.
