I don't think you could read two more divergent opinions on the legacy of the last 8 years than these two. Mr. Brickmeyer seems to be seeing through rose colored glasses of blind conservatism. Even many Republican pundits will admit the last 8 years have been a failure, but not Mr. Brickmeyer. He sees the world as John McCain sees the world, through the lens of Iraq and the illusion of success.
I don't personally understand the conservative mindset, and I don't think the long view of the Bush regime will be kind to Republicans and conservatives.
