This poll backs up my recent argument that bias undoubtedly affects the public’s perception of the news media and that it’s eroding trust in reporting:

Just 17% of voters nationwide believe that most reporters try to offer unbiased coverage of election campaigns. A Rasmussen Reports national telephone survey found that four times as many—68%—believe most reporters try to help the candidate that they want to win.

The perception that reporters are advocates rather than observers is held by 82% of Republicans, 56% of Democrats, and 69% of voters not affiliated with either major party. The skepticism about reporters cuts across income, racial, gender, and age barriers.

Ideologically, political liberals give the least pessimistic assessment of reporters, but even 50% of those on the political left see bias. Thirty-three percent (33%) of liberals believe most reporters try to be objective. Moderates, by a 65% to 17% margin, see reporters as advocates, not scribes. Among political conservatives, only 7% see reporters as objective while 83% believe they are biased.

Looking ahead to the fall campaign, 44% believe most reporters will try to help Obama while only 13% believe that most will try to help McCain. Twenty-four percent (24%) are optimistic enough to believe that most reporters will try to offer unbiased coverage.

Even Democrats tend to believe their candidate will receive better treatment—27% of those in Obama’s party believe most reporters will try to help him win while only 16% believe they will help McCain. A plurality of Democrats—34%—believe most reporters will be unbiased.

Among unaffiliated voters, 44% believe reporters will try to help Obama and 14% believe they will try to help McCain. Seventy percent (70%) of Republicans expect Obama to receive preferential treatment while only 8% believe reporters will try to help McCain.

Voters aren’t as gullible as some in the media seem to think.
