Are you seriously asking whether campaigning does any good??
Ross Perot bought 3,or was it 4 half-hours on network tv. He got 19% of the vote. I think the GOP needs more long-form presentations. You can't counter-act the media's mindless soundbites with our soundbites. I think a Perot-style presentation by McCain on the Freddy Mac, Fannie Mae situation would destroy the Dem's. He hasn't touched it and is getting the blame.
