You may have misunderstood my thrust in as much as I concur with you totally your analysis.
The class elites and their liberal mein as you opine were totally rejected by Dubya, which indeed causes them to despise the man today.
I understood your thrust. I just expanded on it, because it illuminated a piece of the truth.
Historically, Bush's class has stood for noblesse oblige and achievement. The leftist elite despises that concept and, instead, claims the pinnacle for themselves, based on their (supposed) intellectual (and moral) superiority.
Their claims aren't based on any kind of achievement, but on arrogance alone.
And, as you say, they hate Bush. Because, in their world, he should be one of them. But he rejected them, siding with the common people, the businessmen and oil field workers in Midland, Texas. Thus proving his "ignorance" and earning the everlasting animus of the leftist Ivy League elite.
I believe we both know these people and we share a common opinion of them.
