In 1997, in Houston, the John Birch Society rented a hotel conference center to announce that Jimmy Carter, Ronald Reagan, President Bush and Bill Clinton were really insiders working to overthrow the Constitution and nation.Assume for the sake of argument that this is true. That's four consecutive Presidents of both parties. But we notice that the nation and (give or take a Bushian overreach) the Constitution are not yet overthrown. Thus, we are talking about a conspiracy so inept that even with four consecutive Presidents of the US on the payroll, they still can't manage to overthrow the Constitution and nation.
Let's face it: that's a pretty damn pathetic conspiracy. Maybe they should try setting their sights lower -- polluting our precious bodily fluids, or something.
So, frankly, even assuming this is true, I don't think we have anything to worry about.
