CNN doesn't need a license; it's a network, and reaches much of it's audience over cable, which places it outside the FCC's purview in any event. But networks don't need licenses; their local affiliates do. Even so, you should hope that political content never becomes an issue with the FCC under any circumstances, or else it'll be Rush Limbaugh, Glenn Beck, and Laura Ingraham that get their broadcast affiliates licenses pulled, under an FCC appointed by the next Clintonoid president (Hillary or not).
Well said.
