My NationalJournal.com column for the week looks at what we know about whether the rise in cell-phone only households is causing any skew in polling results. The short answer is that polls that cannot reach cell-phone-only voters may be slightly understating support for Obama and overstating support for McCain, although the difference is small (and likely within the margin of error of any individual poll). As the Pew Research Center's Scott Keeter recent told the Arizona Reporter (in a clip received too late to make the column), "For the first time, we’re actually seeing a difference between cell-only voters and land line voters when you take into account age."
I hope you read it all.
