Cell Phone + Drinking = Politically Liberal?

This makes sense in a way, but...regardless of political choices...everyone I know is cell phone dependent and drinks far too much.

FiveThirtyEight: Politics Done Right: Study: Excluding Cellphones Introduces Statistically Significant Bias in Polls:

"Being cellphone-dependent also appears to be significantly correlated with media consumption habits (in particular, getting more of one's news from the Internet and less from television), which also seems to be increasingly important in determining one's political views. And there are some characteristics that may be even more subtle. For instance, there are some hints in the CDC data (such as the higher prevalance of binge drinking) that cellphone-only adults are less 'domestic' and more 'bohemian'. I suspect that, in young adults, this is correlated with more liberal political views."
