Earlier studies — including a joint Pew-AP report two years ago — concluded that cell and landline users had similar enough views that not calling cell users had no major impact on poll findings. The new report concludes that "this assumption is increasingly questionable," especially for young people, who use cells heavily.
Combining polls it conducted in August and September, Pew found that of people under age 30 with only cell phones, 62 percent were Democrats and 28 percent Republicans. Among landline users the same age that gap was narrower: 54 percent Democrats, 36 percent GOP.
Similarly, young cell users preferred Democratic presidential candidate Barack Obama over Republican nominee John McCain by 35 percentage points. For young landline users, it was a smaller 13-point Obama edge.
