As an individual that truly believes and practices core principles espoused by the boglehead community, of course, I would never invest according to who is in power. In fact, folks who DO this in my personal life including colleagues at work promptly receive the butt end of my ridicule. Some of them now, two years later, are starting to admit that I "may" have been right. To each his own, I could care less how anyone else's portfolio is doing. :)
