Bush is Not Incompetent
This article, co-written by George Lakoff of "Don't Think of an Elephant" fame, explores the reframing crucial to actually attacking conservatism rather than easily scapegoating Bush.
The authors argue that although it is easy to attack Bush for his failures, his failures are actually a product of conservative governance. Although Bush won't run again in the next election, another conservative will, so energy should be focussed on speaking out not just against Bush, but against the Neo-Con movement as a whole.
Although it is important to note that speaking out against Bush is a necessary - and can be a creative - exercise.
