That could be true.
In my experience however, most of my friends are a little left of center and damn near all of them are either engineers, IT, or have an MBA. Seems common in Seattle.
I realize this doesn't address the issue of what the breakdown in the organizations are; but I wouldn't think an educated contingency would let people without proven analytical skills run things for them. Just a guess...
Ever looked at the right of center whackjob institutues? MFAs, MDs and DDs (that be divinity - even more applicable than Fine arts......)
