Broad topics we might want to look at

I also definitely agree examining how the media influences voter behaviour (turnout, actual candidate/party choice, etc.) is essential. Seems like a difficult one to phrase, though, as people will likely reveal little more than their biases if you ask "How much does the media influence you politically?"... additionally, "How great of a role do you think the media plays in politics?" (or the like) measures public perception of the media's influence, which isn't necessarily a good measure of the reality. So that question should certainly be worded carefully.
