Donald Trump is indeed a creation of the liberal media. Were they not covering everything he said, wrote or thought about, his bubble would have burst already. As it is, America loves nothing better than sticking it to the NY Times and NBC
Ironically, voting for Trump helps the New York Times, NBC, and the rest of the media. Trump is a ratings bonanza.
Nate Silver
tweeted that Marco Rubio "made 3 above-the-fold headlines at nytimes.com in January. 2 of them were about his boots."
Even the legacy media outlets focus more on the superficial crap that we buy regularly in "reality" shows and celebrity web sites. Rubio (and most of the other candidates) spoke incessantly over many months about policy, and the media ignored him (them). When Ted Cruz made fun of Rubio's boots, the New York Times reported the mockery above the fold on page one. Trump's entire campaign has been of the boot-ridicule variety. And the media have covered every bit of it in nauseating detail.
If anyone is wondering why Rubio (and to a lesser extent, Cruz) is now unleashing tabloid insults at Trump, it's not hard to understand. At this very late moment, it's the only way to get media attention.
All of this says much more about the electorate than it does about the candidates or the media -- not that anyone is off the hook.
