Glenn Reynolds quotes Gregg Easterbrook:

Democratic attacks on Mr. McCain and Republican attacks on Mr. Obama both seek to punish impermissibly positive thoughts. At a time when there exists a sense of crisis over the economy, fuel prices and many other issues, this reinforces the odd, two realities of life in the United States today: The way we are, and the way we think we are. The way we are could use some work, but overall, is pretty good. The way we think we are is terrible, horrible, awful. Possibly worse.

Well, yeah. Check out this recent doomsday riff from David Letterman, who, during the 1980s, despite the equally eeeeevil Reagan being in charge was far too cool and ironic to be this morose about life:

Guys talking about the President really can't do anything about the economy. I don't know if that's true or not, but let's give them that one, let's just say “okay, the President can't do anything about the economy.” Everything else has gone so lousy in the last eight years. I mean – and I'm a guy who doesn't pay attention to much, as long as I got wresting and a TV dinner I'm fine – but even I am perceiving now that things are horrible in ways they shouldn't be horrible. Now, we're not going to impeach the guy. Could we get our money back? Honest to God, what, I mean [audience applause], just at least something.

Dave's clinging bitterness is enough to make you change the channel...And if it's to ABC, you're confronted with more doomsday, as James Lileks notes:

"Are we living in the last century of our civilization? Is it possible that all of our technology, knowledge and wealth cannot save us from ourselves? Could our society actually be heading towards collapse?

"According to many of the world's top scientists, the answer is yes, unless we take action now."

They’re asking for readers to submit their own dystopian nightmares.

What is it with the pessimism of the overclass? If it wasn’t for doom and gloom, they wouldn’t have a reason to live. The latest example comes from ABC News, and suggests that this century may be the last one for civilization. Who says? Scientists! Ah, well, if it’s scientists, we’d best pay heed. Or perhaps you disagree; the century’s still fresh and young. It still has that new century smell. Warranty’s good for another few years, and besides, we haven’t dumped the trunk-junk accumulated in the previous century. We’ll figure something out. We always do.

But you don’t get publicity by suggesting this century might be better than its predecessor, or by asking people to envision how cool the future might be. There are dozens of websites and Flickr sets devoted to retrofuturism, to the art of describing what things might be like. If you grew up in the 60s, you’ll remember all the paintings of space – useful space full of gleaming silver ships. That all ended with “2001: A Space Odyssey” which suggested that the future of space was long, dull, and lonely, punctuated with homicidal computers, trippy FX and enormous wise space-fetuses. Great film, but from then on, something seemed different about the future. Did we really want to live there?

I'm not sure how much of a role Stanley Kubrick's opus played in causing liberalism's turn towards nihilism, but the timing is certainly right; as I noted a couple of years ago in a post titled, "1969: The Shattering of the Modernist Dream".

So is there reason to be optimistic today? Of course. But just don't expect much help in that department from the media, at least until November. They've got the double-whammy of their own industry in dire straits, and an economy to keep talking down, at least until--somehow, miraculously--it begins to turn on a dime the day after the election. (Provided the appropriate audacity and hope and change occurs, of course.)
