The criminal Bush Administration was able to seize power, and maintain power for 5 years largely because they always worked in lock-step. The talking points and strategy of the Republican Party over the past several years was always in-sync. Theirs was a centralized approach to strategy.
As we learned today with the indictment of Libby, that is also what will bring them down. They over-communicated and over-strategized. Too many people knew too much. One slip (the Plame leak and the failed cover-up) will bring down every single one of them like helpless dominos.
