Pew Research Center President Michael Dimock examines the changes – some profound, some subtle – that the U.S. experienced during Barack Obama’s presidency.

Data from Pew Research Center polling this year suggest that the landline-only bias is as large, and potentially even larger, than it was in 2008.
With fully a quarter of the U.S. adult population now relying solely on cell phone service, pollsters and other survey researchers face a difficult decision as to whether to include cell phones in their samples. A joint study by the Pew Research Center for the People & the Press and the Pew Internet & American Life Project takes an up-to-date look at the potential biases in findings based on landline-only surveys.
The mobile nature of wireless phones creates a significant problem for geographic sampling.This problem is exacerbated by the fact that the wireless-only are more geographically mobile than those with landline phones.
The latest study of Pew Research Center election surveys analyzes the effects of conducting both landline and cell phone interviews. While the addition of cell phones had at most a modest effect on estimates of candidate support in individual surveys, when looked at in the aggregate clear patterns emerge.

A new Pew study finds that on key political measures such as presidential approval, Iraq policy, presidential primary voter preference and party affiliation, respondents reached on cell phones hold attitudes very similar to those reached on landline telephones.
