The Left has News/Entertainment Media as their vehicle and the Right has talk Radio-- but Talk Radio cannot scale in participation. Youtube and other internet-based communication sites can scale really well but it is not currently channeled, not organized. The good news is that it is slowly but surely taking shape, taking form, getting organized into a common direction; and the scale is MASSIVE.
The Left has seen nothing yet; the Left is hand-wringing over talk radio and Fox but that is a pebble compared to the mountain or the iceberg of conservatism that is self-assembling. You know who gets it? Breitbart. He gets it, he really does get it. You know who the only politician that gets it? Palin. And maybe Gingrich.
The conservative politician that breaks away from the myth that they need the permission of Leftist Media to get elected will be the politician of most influence in the future. You will know who that politician is when they feel no compulsion to enter into the Leftists' pits of Sunday talk shows.
