Here is an interesting website that aggregates news items about both US presidential candidates and visualizes that data providing a nice dashboard-like “snapshot”. Once you click on a bar or candidate name, it shows you word-sized historical graphs (sparklines) of their popularity. For more information on sparklines or other ways of visualizing data, see Edward Tufte.
