We've listened to all the hullabaloo about the new online political order. But long-shot Democratic presidential candidate Joe Biden has taken a decidedly old school tack in the run-up to the January 3 Iowa caucuses: full-page black-and-white newspaper ads.

The venerable Iowa Poll found that 82 percent of likely Democratic caucus-goers read newspapers to get campaign information. Says Biden senior strategist John Marttila: "Caucusgoers are high news consumers. They read print."
