Mainstream news coverage does not reflect the political make-up of the Democrats and Republicans in Congress. Mainstream media is exceedingly likely to cover news through a partisan filter. So it’s no surprise that liberals and conservatives are polarized when it comes to news sources they trust and utilize.
In 2019, Media Research Center analyzed 540 hours of news coverage on CNN and MSNBC over three randomly-selected weeks. The two networks conducted nearly the same number of interviews with members of Congress. In total, they interviewed 284 Democratic members of congress compared to just 40 Republican. MSNBC leaned even more to the left, as they interviewed 148 Democrats and only 11 republicans.
Both networks gave opposing questions to the Republicans but gave friendly questions to the Democrats. Meaning, they focused on Democratic talking points and agendas.
It’s common practice to ask a political interviewee to give an answer to the argument of the opposite side, but consistently asking Republicans to answer to Democratic talking points, while hardly ever asking Democrats to do the same thing, speaks to the fact that the networks are actually choosing sides.
Eric Merkley, a contributor to the American Politics and Policy website who specializes in public opinion and political communication, recently studied 400,000 news stories on economics published over three decades and found that the mainstream portrayed liberal politicians in a better light than their conservative colleagues.
The news stories were on unemployment and inflation between 1985 and 2013 from the Associated Press and a variety of mainstream newspapers, including the New York Times, USA Today, and those with histories of backing the Republican Party, such as the Dallas Morning News and the San Diego Union-Tribune.
He found that the tenor on economic news is more favorable during Democratic presidencies compared to Republican. He also found that only Republican administrations are treated with more negative coverage in response to short-term increases in unemployment or the inflation rate.
