Many of the polls that we have been consuming voraciously have not included people without a land line (like me). In the figure below, we can see what a difference that makes in the results. Yellow bars are polls that included cell phones and grey bars are polls that did not. Those that excluded cell phones are significantly skewed towards McCain, and falsely so insofar as people without a landline vote.

Well I don't know what to make of this. Does this mean that folks who only have cell phones tend to be more on the left?

People that fear change are less likely to try new things such as cell phones. An internet poll would likely show a higher progressive percentage than one taken in churches.
