This is an excellent quote from Red State! It explains how many in the media report on Trump and Republicans.
On a nearly constant basis, reporters for major, traditional media outlets have grabbed on to a story and run with it, only for that story to collapse under the weight of its own bull@#$%. Each and every time, almost without fail, the retractions have been quiet and not discussed with the level of fanfare that the original stories were given.
When it fits a narrative, they shoot first, ask questions later. All the while, left wing faithful spread the story across social media with lightning speed. Yet the correction or retraction languishes on page J5 of the local paper or buried in cyberspace. This is how you operate journalistic hit squads.
