This opinion piece: http://www.irishtimes.com/opinion/kathy-sheridan-the-media-got-it-right-on-trump-but-nobody-cares-1.2877809 is clearly just one angle rather than a comprehensive assessment of why Trump won. This is partly because The Irish Times wants to write more than one article about Trump.
Anyway, the US media made Trump. The Irish Times and the rest of the Irish media are obsessed with Trump – just like the US media.
Of course the media, as a group, want to say they had no part in Trump’s victory, but it’s just not true. What Trump understands about publicity is that all publicity is good publicity in US politics. People, after having a candidate thrust into their faces for a year and a half, forget why they know the candidate’s name but they sure as hell remember that person’s name, and hey, what’s he promising? Change? That doesn’t sound bad to them.
