The below is Kurt Klein's comment following the GVP post, "Gore Vidal’s ‘Burr’ Is Antidote to Tea Party Myths - Bloomberg"
Vidal emphasized the founders' flaws to counter the hagiographic myths that had grown up around them. He adopted Burr's voice to do so, because as the loser in the power struggle, Burr had a motive for putting them in a bad light (he was the American Revolution's Trotsky). But I don't think Vidal simply dismissed them as a bunch of men on the make, though they certainly were that. His whole political attitude of revering the "American Republic" and decrying the "American Empire" makes no sense unless he fundamentally admired the principles of the men who created that republic. He simply refused to treat them as plaster saints.
