Obama's lead bigger when cellphones included in the polling.

clipped from blog.wired.com Political polls that include cell phone users show Obama leading McCain by an average of 10 points, versus just over five points in land-line-only surveys, notes a Sunday survey put together by Nate Silver, founder of the electoral projections site FiveThirtyEight. The survey confirms a trend that the Pew Research Center noted late this September, although the differences between the surveys with and without cell phones was not statistically significant at that point.
