The candidates have spent a year and tens of millions of dollars in Iowa, and Thursday night the first actual voters offered their first assessments. Some candidates and their strategists were hoping the caucuses and the New Hampshire primary next week would settle the race, weeding out the contenders for the two major parties’ presidential nominations. Watching the campaign in cold, snowy and mostly empty Iowa, we were hoping for something else  that this year’s Iowa-New Hampshire rush to judgment will be the last.

For all of Thursday night’s drama, the results in Iowa did not preclude a race going into New Hampshire, and, we hope, beyond  to South Carolina, Florida and the cluster of primaries on Feb. 5. Barack Obama beat Hillary Clinton, but she’s got plenty of money left, and John Edwards got a boost. Mike Huckabee’s win was unlikely to deter Mitt Romney or the Republicans who did not contest Iowa: John McCain and Rudolph Giuliani.

Keeping this race alive so significant numbers of Americans in more populated states can participate would begin to make up for the ludicrous spectacle of the past year, which enriched the television networks and the political consultants (some $300 million already spent) far more than it enriched the political dialogue. We hope both parties will wake up and end the undemocratic system in which the choice of a new president rests far too heavily on nonbinding votes in January by voters that don’t necessarily represent the rest of the country.

We don’t question the enthusiasm or the commitment of the people of Iowa and New Hampshire. But Iowa, where a huge turnout amounts to less than 10 percent of the population, is about 92 percent white, more rural and older than the rest of the nation. New Hampshire has a non-Hispanic white population of about 95 percent. Iowa’s Democrats are more liberal and more protectionist than the nation’s Democrats. Its Republicans are more conservative, and religiously driven, than the nation’s Republicans. And yet, The Boston Globe reported that Mr. Romney spent $7 million on ads in Iowa. That’s nearly $4 per registered voter.
