The left wing seems to know no bounds in its efforts to ideologically cleanse CNN of any seemingly rational point-of-view when it comes to the issues of the day.

Although liberal were successful in their effort to rid the network of Lou Dobbs, some elements are now hung up on also eliminating recently hired contributor Erick Erickson from CNN's programming.

And now a liberal group called Campaign for America's Future (CAF) is attacking CNN for planning to air a documentary called "I.O.U.S.A.: Solutions," suggesting the network is "fanning the flames of deficit hysteria." The group's co-director Roger Hickey is demanding CNN impose a "Fairness Doctrine" on itself.

"This weekend, CNN is giving four hours of free airtime to the leading propagandist fanning the flames of deficit hysteria, Pete Peterson, along with his lackeys," Hickey wrote in an e-mail sent to supporters and also posted on the Huffington Post. "[A]nd if they do go ahead with this programming, tell them to provide balance to Pete Peterson's deficit hysteria. Give equal time to defenders of Social Security, Medicare and public investment."
