The media is involved in every aspect of your life and has more of a say than one might think.
Media sources don't just report about what's happening they introduce bias. How much a source chooses to cover something, or how they choose to cover it can change a whole communities perception. For example, today's news page has more than 1 article in the top 5 about how politicians are trying to sue the media, or about media bias.
Media is a double edged sword and journalists should be conscious of this fact by reporting all the facts.
But that begs the question, should media be biased when reporting on politics. My personal take is this: they can create contentions based on facts but not solely based on opinions. In fact I think it is important to have informative disagreements because it creates more discourse on controversial political topics. In fact, the media's ability to create discourse on a topic is important in informing the public. Often times people tend to ignore problems and discourse may be able to solve that.
Problematically, media sources often create dangerous false narratives that tends to decrease trust with in the public. Especially during electing time.
Not only is this dangerous but this defines a whole new problem, how do voters react to this bias in the media? I believe the increased media involvement in politics can seek to educate those who are not overly politically involved about the major contenders and problems surrounding them. Unfortunately, the smaller ticket candidates get left out. But this also serves a greater purpose, when a candidate is not fit to be president people are more likely to learn through the media sources. In that way, media keeps people accountable for their actions. The simple threat of the media creates more ethical politics than there would be without it.
Ultimately, it is important to be conscious of the impacts of media bias in politics while forming your own opinions but the media is necessary to making sure democracy is not corrupt.
