Shorter McIlheran: "The left" is ultimately blameworthy for Barack Obama's depiction as a banana-eating cartoon monkey because "the left" spent eight years comparing George Bush to a chimpanzee.
McIlheran is correct to take offense with the latter comparison, as it unjustly maligns our noble cousins, the chimpanzees.
To be sure, Kingdom Metazoa suffers as a whole when any of them is compared to a politician. Or a newspaper columnist.
Elsewhere: Obama not a sufficiently typical American.
