Wired News points out a growing issue troubling political polling groups like Zogby and Gallup: they don't call people on cell phones. That might sound like a positive thing at first, but consider the number of people who use only mobile phones and don't have a land line (about 3% of Americans at the moment). That means an entire segment of the population - early adopters - aren't being represented in these polls.
By 2009 as many as 15 percent of Americans are predicted to have tossed their land line phone, meaning 1 in 7 adults wouldn't be included in these polls.
