Unruly Media has put together a nifty dynamic infographic that tracks videos from the official Obama and Romney campaigns, as well as the 12 Super-PACs that are most active in this year’s contest. It also has the 10 most-shared clips for each candidate over the past seven days; so far, the President is leading more than two to one in YouTube views, and more than three to two in total shares, though Romney leads is in YouTube comments, implying that his videos are the subject of more debate.
