Just wait until after the convention. Between Kerry being in a Vietnam/Cambodia lie-filled quagmire and the GOP convention, Bush should be riding high going into the debates.
I'm cautiously optimistic GWB will pull this thing out in the end, but I certainly don't think the convention will have anything to do with it.
Dan Blather & Co. have already made the decision NOT to carry the opening night heavyweights (Guiliani, et al), and I have no doubt the focus of coverage will be on protesters and "the large number of Pat Robertson evangelicals in this convention center."
I'll be watching C-Span for unfettered coverage, but I'm not expecting the sheeple to do the same.
