I think there may be something to this article. I remember saying a few months ago, social media could pad Democratic turnout in ways not seen in the pre-Facebook era. It's not like people can now put their heads in the sand and not realize there is an election. Plus, I know some core Democratic constitiences -- African-Americans, Hispanics gays, single women -- used Facebook to apply not only pressure that their friends vote, but vote for candidates they viewed as being in their self interest.
