From FiveThirtyEight.com, a graph showing Obama's national lead in various polls, with the yellow polls involving both landline and cell phone polling while the gray polls only involving landline polling.
Notice a pattern?
I've been saying this since the primary election ended back in June: polling conducted without the inclusion of cell phone lines is no longer an acceptable standard. Not only has cell phone use largely eclipsed landline phone use for people that still own both, but many of the younger generations have stopped subscribing to landline phone service completely (including myself).
Wake up polling industry, before you end up giving another "win" to Dewey.
