The Center for Media and Public Affairs latest assessment of network campaign coverage is out. The findings? The major networks all tilt anti-Bush in their coverage, but ABC is the worst. From Sept. 7 to Oct. 1, the networks cave positive coverage of John Kerry 38 percent of the time, but positive coverage of Bush only 29 percent of the time. ABC’s pro-Bush coverage was the lowest at 20 percent. CMPA finds Fox’s “Special Report” tilts a little toward Bush, but is more balanced in its coverage than the networks.
