Justice for Bush/Cheney?

I read here and there that Bush/Cheney will simply not allow a Democratic victory in the 2004 Presidential election, because they are afraid of what honest investigations under a Democratic President (and maybe Senate) would turn up about them. According to this idea, the fear of criminal prosecution would lead them to declare martial law or something of that nature. I've no doubt that there is a real and massive basis for criminal prosecutions, but I also cannot imagine the Washington political establishment tolerating it. I can just hear the Davids Broder and Gergen now, talking about the need for healing and closure and what-not, and how people need to still believe that all their leaders were honorable. Does anyone believe that there would be a real possibility of an honest investigation of what this Addministration has done? Or would 'bipartisan' backscratching and mutual protection rule as always?
