Do Polls Miss Obama Voters With No Land Line?
US News & World Report, September 29, 2008
In three surveys this summer, The Pew Research Center for the People and the Press contacted users of traditional land lines and of cell phones.
Each time, Obama came out 2 to 3 percentage points higher than when Pew called land lines alone.
Nearly half of 18-to-29-year-olds are strictly wireless.
Cell-only youths tend to be
• at the younger end of the group,
• more likely to be unmarried, and
• more mobile than those on land lines.
Gallup polls also call cell phones as well as land lines.
New York Times/CBS pollsters also call cell phones as well as land lines.
An ABC News/Washington Post poll last week found that calling cell phones affects poll results only negligibly.
