As I have discussed here and here, an attempt seems to be going on to subtly revise history so that people forget George W. Bush was President on 9/11. 

One question I didn’t address in the earlier posts is: Who is doing it? Now, you might think it’s obviously the Republican party doing it, as part of an effort to rehabilitate the image of Republicans as better at National Defense. This is quite likely, although it seems like it would be simpler to demonize Bush, and claim that his Presidency is not typical of Republican ideology. 

But is there any other group that would have an incentive to make this effort?
