My concern is then the composition of the rich content when Google offers itself as the platform. "Welcome, to our podium, Canditate A. We've already constructed the stage and backdrop, too, with these accompanying articles, images, and layout."

It sounds, initially, like Google's role is very passive, but I think control over what surrounds the podium has the potential to be very active. "Hey, Candidate B has better lighting!"

Google as active medium becomes the active message? Thoughts?
