I don't think the "Bushes" are actually in charge of diddly-squat. It's one of the reasons my "hating" them is so ludicrous and it's a primary reason they just sail along so placidly whether they're on top of the world or getting squashed like a bug by the likes of Clinton. They're raking it in, they get to play power-monger, people pay them to fly all over the world and get treated like royalty ... what spoiled frat boy of a politician/banker's son wouldn't like -- or feel somehow entitled to -- that sort of life?
I think they've got lots of power, lots of connections and even some firm ideas on what they want. But I don't think they've set out to rule the world (or even the United States) ... certainly not by trying to assassinate Reagan.
They aren't the deepest of thinkers. Listen to them speak.
