Don't agree. Can be done. Reagan and slick Willy did it. It would take effort by Bush since he is such a poor communicator but he could at least get the message out directly to his consitituencies and get support for war etc. up to 50% or so.
Perhaps you've forgotten that Reagan was continually excoriated by the MSM. His popularity came despite the negative coverage. Perhaps it's an example of the old saying that "there's no such thing as bad publicity."
