I'm probably not the best test case for this question based on many of my posts and comments around here, but an article in Science magazine posits that conservatives are "happier" than liberals. Or, at least, residents of "red" states feel happier than residents of "blue" states. The New York Times, riffing in a story about the study, says of to its home-state readers:

It’s rather dismal. If there were a National Happy League, we’d be the New Jersey Nets. We’re No. 51 out of 51 [Ed note: The District of Columbia was polled to get the list to 51].

This is an enormous generalization, but I've long thought that was true — that liberals are grumpier (or at least have less mirth and joy in their lives) than liberals conservatives — based on anecdotal evidence, my observations of political discourse over many years spanning all sorts of varieties of who is "in power," personal experience, and other reasons I won't get into here ... at least not at this late hour. But, it appears that the polling data says says so, too, when it gauges "Gross National Happiness." As John J. Miller at The Corner says:

One snap conclusion, from scanning the list: Red states are happy, blue states are sad (relatively speaking). Make of this what you will.

And I suspect that we might make something of that conclusion around here. That all said and shared, I'm sure Joel and Khabalox will disagree with that study — and, in fact, insist that the opposite is true — yet still have a joyous Christmas. At least I hope so, because I wish it upon them.
