A common tendency in human behavior is to act in the way we were most recently reinforced to act -- or not to act.
Last time around, the Republicans picked a physically unattractive war hero who had been a young hellion and screwup and who'd been married twice to be their Presidential candidate. He, in turn, picked a sexy woman with more spunk than know-how as his running mate.
Their campaign fell short.
This time, the Republicans picked a handsome man who'd never been in the military, who has lived his life on the straight and narrow, and who has been married to the same woman for 43 years. He, in turn, picked a nerdy-looking, well-mannered budget wonk as his running mate.
We have yet to see how this campaign will turn out.
But if it doesn't turn out well, at least it won't be for the same reasons as last time.
