In an audiotape of a private meeting with aides leaked to the LA Times, the Governor of California points out to them that Californai Republican assemblywoman Bonnie Garcia is not Mexican, but is of Caribbean descent (her parents were from Puerto Rico):
"I mean, they are all very hot. … They have the, you know, part of the black blood in them and part of the Latino blood in them that together makes it," he says..
Schwarzenegger went on to say his friend, Cuban-born former weightlifter Sergio Oliva, is the same way...
A spokeswoman for Schwarzenegger said the conversation was in good fun. The remarks, she said, were taken out of context.
Garcia herself said that she is not bothered at all by Schwarzenegger's comments. She said she has an inside joke with the governor in which she calls herself a "hot-blooded Latina" who is passionate about issues.
Indeed, Schwarzenegger is right that Caribbean Hispanics tend to be on average part black: Here's a triangle created by geneticists Shriver, Parra, and Kittles which shows Puerto Ricans are tri-racially mixed, while Mexican-Americans are primarily European, significantly Indian, and only slightly African.
As Schwarzenegger implied, the more outgoing African personality contribution in Puerto Ricans makes them more extroverted on average that Mexicans, whose Native American contribution inclines them toward solidity and introversion. (Spaniards tend to be fairly extroverted so mestizo come in a wide range of introversion to extroversion while mulatto are more consistently extroverted.
Mexicans are apparently about 3 to 8 percent African, but that has been lost in the idealization of the mestizo of Comsic Race by the Mexican government.
