Cell Phones and Polls

From Pew:

"In the current poll, cell-only respondents are significantly more likely than either the landline respondents or the cell-mostly respondents to support Barack Obama and Democratic candidates for Congress this fall. They also are substantially less likely to be registered to vote and - among registered voters - somewhat less likely to say they are absolutely certain they will vote. Despite their demographic differences with the landline respondents, the cell-mostly group is not significantly different from the landline respondents politically."

Bear in mind, too, that because cell phone users pay more directly for every minute they talk, they are probably far, far less likely to answer for a pollster (or any "unknown" number). So, even these numbers are skewed somewhat.
