Many Democrats, as always, are caught in their insular liberal information loop. They think the polls are bad simply because the economy is bad. They tell each other health care is unpopular because the people aren’t sophisticated enough to understand it. Some believe they can still pass health care even if their candidate, Martha Coakley, loses the Senate race in Massachusetts on Tuesday.

That, of course, would be political suicide. It would be the act of a party so arrogant, elitist and contemptuous of popular wisdom that it would not deserve to govern. Marie Antoinette would applaud, but voters would rage.

The American people are not always right, but their basic sense of equilibrium is worthy of the profoundest respect. President Obama has shown himself to be a fine administrator, but he erred in trying to make himself the irreplaceable man in nearly ever sphere of public life. He erred in not sensing that even a pragmatic government could seem imperious and alarming.
