There's a lot of wizardry at CNN these days. There's Wolf Blitzer and his enchanted beard. There's Andersen Cooper and the mystical way he made everyone forget that he was ever the host of a reality show. And then there's John King and his magic board of election elucidation.
The "multi-touch board" itself is a marvel of modern technology. It works much like the virtual screens that Tom Cruise used in Minority Report, where you wave your hands over a display, and things move around and change. As compared to Tim Russert's white board and marker setup back in 2004, it's like an ice farmer and a Frigidaire (one with satellite TV in the door, inventory management, and internet access to e-mail your shopping lists to Safeway).
