Wise words in an essay by John Hodgman, who plays public pomposity, but who, evidently, is a private thinker. It appears in the 90 days, 90 reasons project: a daily dose of reasons to reelect the president. I think he means to address those liberals who're disappointed in Barack Obama because (I told you so) he's not liberal enough, and a pragmatist. People who want it all, now; and, failing that, are willing to let the other side win.
It's worth a read in its entirety; as a bonus, as you'd expect from him, it's funny and witty, too.
