Americans simply don’t trust the media, particularly when it comes to politics. Swing-state polling from The Post and the Schar School of Policy and Government at George Mason University found that only 3 in 10 residents of six of the most important states in this year’s presidential election trust that the media will fairly and accurately report political news. Seven in 10 indicated that they had not too much trust in that occurring — or that they had no trust at all.
