I don't think George W. Bush is a racist
The sins of George W. Bush could keep an army of Shakespeares and Sophocleses busy forever.
The essence of his party is the tribal-supremacy fantasy of rich, white, authoritarian, nationalistic, Christian men.
As LBJ famously said when signing the Civil Rights Act, "We have lost the South for a generation." Turns out that was an understatement.
And yet, I'm unaware of any evidence that Bush judges people on the color of their skin.
He has no qualms about putting minorities into senior Cabinet positions, even those with acute memory problems.
He seems to delight in Tex-Mex culture, and I see no reason to believe he thinks ill of his Mexican sister-in-law.
The only time he was out of step with the rest of his party was when he didn't play unflinching hardball on immigration policy.
What Dubya is is a classist.
To a large extent, that can be a purely academic distinction. In a white man's world of class and privilege, skin color/ethnicity and class make a rather tight Venn diagram. Thus, his economic, criminal-justice, and military policies are effectively racist, whether or not that's his specific motive.
Further, he's evidenced zero qualms about the way his minions have exploited race to bring him to power, whether it be Karl Rove's "black baby" push polls to topple McCain or myriad dirty tricks to suppress black voting.
But all evidence suggests that he's an equal-opportunity sociopath, caring little for anyone lacking the good sense to be a well-connected Republican (ideally Judeo-Christian, though the Bushes are happy to consider many Muslim despots among their closest friends).
He's content to have policies that drown New Orleanians and Minnesotans, so long as money and power keep flowing to the moneyed and powerful.
At the very least, he's insufficiently racist for the GOP base. So, whether you agree with my premise or not, consider this: the worst president ever may be the least racist guy they've got.
