But it was not to be. Indeed, the Biden campaign was covered more for its missteps than anything else. Chris Dodd, also a serious candidate with a distinguished record, received much the same treatment. I suspect that there was more coverage of the burglary at his campaign office in Hartford than of any other single event during his run other than his entering and leaving the campaign.

Who is responsible for the veil of silence over Senator Biden? Or Senator Dodd? Or Gov. Tom Vilsack? Or Senator Sam Brownback on the Republican side?

The decision was probably made by the same people who decided that Fred Thompson was a serious candidate. Articles purporting to be news spent thousands upon thousands of words contemplating whether he would enter the race, to the point that before he even entered, he was running second in the national polls for the Republican nomination. Second place! And he had not done or said anything that would allow anyone to conclude he was a serious candidate. A major weekly news magazine put Mr. Thompson on its cover, asking — honestly! — whether the absence of a serious campaign and commitment to raising money or getting his policies out was itself a strategy.

I’m not the only one who noticed this shallow news coverage. A report by the Project for Excellence in Journalism and the Shorenstein Center on the Press, Politics and Public Policy found that during the early months of the 2008 presidential campaign, 63 percent of the campaign stories focused on political strategy while only 15 percent discussed the candidates’ ideas and proposals.

Watching the campaign unfold, I saw how the press gravitated toward a narrative template for the campaign, searching out characters as if for a novel: on one side, a self-described 9/11 hero with a colorful personal life, a former senator who had played a president in the movies, a genuine war hero with a stunning wife and an intriguing temperament, and a handsome governor with a beautiful family and a high school sweetheart as his bride. And on the other side, a senator who had been first lady, a young African-American senator with an Ivy League diploma, a Hispanic governor with a self-deprecating sense of humor and even a former senator from the South standing loyally beside his ill wife. Issues that could make a difference in the lives of Americans didn’t fit into the narrative template and, therefore, took a back seat to these superficialities.

News is different from other programming on television or other content in print. It is essential to an informed electorate. And an informed electorate is essential to freedom itself. But as long as corporations to which news gathering is not the primary source of income or expertise get to decide what information about the candidates “sells,” we are not functioning as well as we could if we had the engaged, skeptical press we deserve.
