Nate Silver, founder of the electoral projections site FiveThirtyEight, organized a survey that concludes 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, Wired reports.

“The survey shows a snapshot of 15 polls conducted on behalf of media companies and by polling companies such as Gallup and Zogby. Six of those, including one released late Sunday by NBC and the Wall Street Journal, include cell phone users. The rest don’t.”

The survey highlights a trend noted back in September but is still too statistically inaccurate to really predict anything, the report said.
