I didn't intentionally leave out 1987. I am certain that if the left is planning the future while the right becomes obsessed with the past, there will be no contest.
The left set out to destroy the world of the past. They have done that. Now, we are to march off to the future singing, we will overcome. You are correct though. We have been changed, and the change is permanent. The people have changed. And, it is the people who control the nation and the future. The brave new world had better be a good place. But, I suspect that the only conservatives allowed there will be the neo-conservatives. There will not be a place for love of country, morality, or truly spiritual things in that world.
