Media bias.

From Gallup:

Today, there is much more controversy among Americans about the media's coverage of Palin. More than half are dissatisfied with the nature of coverage of her, saying it is either too positive or too negative. This seems to reflect the raging political pundit debate over whether the media's commentary on Palin's governmental qualifications and personal life has gone too far.

Whether valid, or merely a political tactic, the election-year shots at the media for biased coverage seem to be eroding public confidence in the entire news media as a reputable institution.
