Do you ever have the passing thought that the presidential election doesn’t matter as much as we think? Whoever wins will govern within more of less the same limits, both domestically and internationally. A New York liberal leaning toward Mr. McCain told me this week he has no fear that Mr. McCain may be a more militant figure than Mr. Obama. We already have two wars, “we’re out of army.” Even if Mr. McCain wanted a war, he said, he couldn’t start one.

I wonder if we follow the election so passionately because we’re afraid. We’re afraid a lot of our national problems are intractable, and the future too full of challenge.

We cannot tolerate feeling this way. So we make believe the election can change everything. And we follow it passionately to convince ourselves its outcome will be decisive and make everything better. We reassure ourselves with pictures of the cheering crowds at the rally. We even find some comfort in the latest story of the latest dirty trick. But deep inside we think: Ah, that won’t work either.
