Is CNN trying to cover politics with a showbiz twist? The network, which has been shooting pilots with fresher faces and flashier formats, did one yesterday in TMZ-like style with chatter from producers. “John King USA” executive producer Michelle Jaconi audi tioned along with producers Paul Steinhauser, Peter Hamby, Mark Preston and Shannon Travis. Sunday, it taped a revival of “Capital Gang,” a political roundtable canned in 2005. Bubbly correspondent Jessica Yellin tried her hand as an anchor. A CNN rep said, “This reinforces the fact that we shoot pilots all of the time.”
