Could one (crudely) estimate an economic value to the right-wing pull of major media? In other words, with what deficit does a Democratic Presidential candidate begin, if the candidate runs even slightly to the left of the political line of the Washington Post, which trashes Obama for supporting a timetable for withdrawal from Iraq, even though this is the position of the majority of Americans and Iraqis, the majority of Congress, the majority of Iraqi parliamentarians? By how much does such a candidate have to outspend his Republican opponent in order to equalize, when this pull is taken into account?
Here are a few ideas to begin:
FAIR and others have done studies of the right-wing bias in the media. One could estimate the economic value of the bias in those institutions that have been studied in this way.
A friend who works at an NGO in Washington tells me that there's a paid service you can subscribe to that tracks your appearances in the media and reports an economic value for them (i.e. what would you have had to pay if you purchased that time as advertising.)
Do folks have other ideas for how to go about estimating this?
