Breitbart has gone full anti Trump all the time

15. It's hard to judge, especially in the russian bot farm era, but

consider that back in February, Breitbart was receiving an average of 45 million unique visitors per month, eclisping ESPN, Fox News and even PornHub. 45 million is a third of the population that voted for either of the main party candidates in 2016.

Also consider the increasingly frequent dynamic of people saying that only they are covering the stories they care about. The depth of the problem only becomes readily apparent when one realizes that they reach a third of the electorate, and quite possibly the vast majority of that audience does not recognize it as the propaganda that it is.

We've all known about the right-wing echo chamber for a long time now, but Breitbart has taken us (with help from Trump) to a point where a considerable chunk of the population consider as "fake news" all media that is not covering breathlessly whatever outrageous bullshit is making the rounds on outlets like Breitbart. If it's not either anti-liberal or pro-fascism to the point of rejection of reality, it's pure left wing propaganda, as far as these folks are concerned.

By extension, yes, its influence most certainly does extend to Congress. Whether or not the folks in Congress actually believe the bullshit peddled by Breitbart and the like, they are very visibly too cowed to forcefully reject people who buy into such bullshit, and risk mobilizing the Tea Party against them. Just look at the number of establishment Republicans who were turfed out of office after being primaried from their right flank.
