Harvard historian James T. Kloppenberg has. He has a book coming out on the President's intellectual evolution, Reading Obama: Dreams, Hopes, and the American Political Tradition. Kloppenberg finds our President is a classically American pragmatist, a "philosopher president" like Jefferson, Madison, both Adamses, Lincoln, and Wilson. He finds a man dedicated like our Founding fathers to promoting civic discourse.
He does not find a socialist:
Conservatives who argue that Mr. Obama is a socialist or an anti-colonialist (as Dinesh D’Souza does in his book “The Roots of Obama’s Rage”) are far off the mark, he said.
“Adams and Jefferson were the only anti-colonialists whom Obama has been affected by,” he told the audience in New York. “He has a profound love of America.”
And his opposition to inequality stems from Puritan preachers and the social gospel rather than socialism [Patricia Cohen, "In Writings of Obama, a City Is Unearthed," New York Times, 2010.10.27].
By Kloppenberg's analysis, President Barack Obama is not some outsider trying to disrupt the American Dream. President Obama is a product and proponent of the American Dream, trying to make America live up to its founding ideals.
