If we’re going to have a conversation about Trump’s assertions of being misrepresented by the media and ‘post truth’ politics and all that shebang then the media have to accept that they opened the door. Politicians lie. We know they do . They do it all the time and they have done so, almost certainly, forever. Politicians are among the most distrusted people in society. The press are not far behind. Politicians lie because they know that the media don’t hold them to account. Some of the media might but a whole load of them won’t and in that conflict the truth is of less importance than the headlines.
