"Mainstream media journalists simply lack the tool set to deal with a candidate like Trump."
They don't? As far as I can tell, the only "tool set" they require is some minimal respect for the truth, and an ability to feel a bit of outrage at the thought of collaborating in the effort to put a lying, racist bully in charge of the country. And that is a tool set which every marginally decent person on earth has.
There, Josh. I managed to make my point in just a couple of sentences, not two thousand words. And it has the virtue of being true, instead of being another weak attempt to deny what is really going on. The mainstream press is owned by Republicans, and it exists to push Republican candidates and Republican schemes. It hires people who are willing to do that by any means necessary. The world is filled with characters who will sell their souls for a comfortable job, and that is what is going on here, not a bunch of over-educated fools that just can't get their minds around the idea that there is a difference between truth and falsity.
