By now you may have read the big article in the Washington Post, examining the state of a failed president who is too self-absorbed to feel as beleagured as he actually is. At this point, the article tells us, Bush is focused on Iraq to the exclusion of everything else, convinced that his legacy will ride upon that war alone.
It's also true that for a two term president who enjoyed GOP congressional control for several years, he really does have remarkably few legislative accomplishments. Where other leaders would have seen an opportunity to push a governing agenda, Bush saw an opportunity to evade congressional oversight as he used the executive branch to commit crimes against the constitution, fill many executive agencies with incompetents, and fill others with people who helped his campaigns' financial backers rob the public. Which leads us to what's probably the most important aspect of Bush's non-Iraq legacy, his decision to provide an elegant demonstration of public choice theory and destroy public faith in the possibility of government action by showing exactly how poorly a government can be run.Yglesias goes on to list some of the failures.
