I have seen people (on the right) compare Bush to Lincohn (some people then thought him was a bad president too). It is a cute argument, but I just don't believe it.
I agree with you that it's crucial for him to win this war. That's one of the reasons he keeps sending troops there, but I think he is selfish and irresponsible. Moreover, it definitely takes a miracle for Bush to succeed in Iraq. :)
