The Causal Arrow

There's much that is interesting in this poll and article by Rasmussen, but it's the headline that most drew my attention. Why assume that which cable news network you watch might affect your vote, rather than how you vote might affect which cable news network you watch (if you're among the minority that watch cable news at all, that is. . . . .). Notice that they imply causation, without demonstrating it, and assume it goes only in one direction.
