http://journalism.about.com/b/2007/10/30/is-the-full-story-being-told-on-campaign-2008.htm# Overall, Democrats also have received more positive coverage than Republicans (35% of stories vs. 26%), while Republicans received more negative coverage than Democrats (35% vs. 26%). For both parties, a plurality of stories, 39%, were neutral or balanced.
# Most of that difference in tone, however, can be attributed to the friendly coverage of Obama (47% positive) and the critical coverage of McCain (just 12% positive.) When those two candidates are removed from the field, the tone of coverage for the two parties is virtually identical.
