Michael Barone tries to explain why Americans are in such a "negative mood".
But he fails.
Here's my explanation: the Baby Boomers are getting older. Old age is challenging enough, but some of my generation thought they were going to Save the World through political action. And they have recently discovered, to their horror, that they are not going to. As Adlai Stevenson quipped about a different political party in 1952, they are "out of patience, out of sorts and out of office."
