Biased Treatment? Never!

It is interesting to me how we aren't hearing much about policy differences in the campaigns. We hear of age differences, of style differences, of speaking ability differences -- but we're not debating the merits of policy positions.

Is it a press bias that is seeking to enhance the favorable aspects of their chosen candidate? Or, is it because there is little difference in their positions? Or, is it an avoidance of substance by the candidates themselves because of the fear of alienating a particular interest group? I suspect the latter.
