Tribalism, a Human Species Instinct

Here are the results of a Zogby Poll. I am not an expert on polling but Zogby seems to be both respected and well known as a useful source of information.

It baffles me that more than a third of those polled still support McCain.

That has to be at bottom a response which can only be described as tribal; tribal in the sense of never defying the tribal chief, and pledging one's allegiance to the chief no matter what.

This is still a very human reaction to threats on our borders, borders being our own small place. We understand that there is strength in numbers, a survival instinct inherited genetically from those life forms which preceeded us.
