Is this why polling was so skewed?

I'm not exactly sure it makes sense so help me think through this (seeing as how I can only think of a couple of unsure reasons why this would be), but I am considering the idea that the polls were so off because more and more olds now have cellphones instead of land-lines.

In the past this has led to samples being less Democratic than the electorate would appear, but as cell phones become more prevalent and affordable, is it possible that even the older demographics are now going off the grid en masse, and are therefore less accessible to pollsters? It actually does make a bit more sense to me that middle-class olds are likely adopting the tech in much higher numbers than they would have been just a few years old (when mainly wealthy olds would have been the predominant group possessing them), leaving mainly the poor more represented in land-line polling, who would probably skew more Democratic.

Naw.

Care to elaborate then, preferably sans Bush-era conspiracy theory?
