The media is primarily in the entertainment business, and Donald Trump is an entertaining clown -- for some.
For the most part, the broadcast news organizations are lazy. It's easier to follow the Republican horse race and wallow in gossip and trivia than to deal with legitimate issues. The next time Donald Trump says something of substance will be the first, and if it ever happens, the so-called broadcast journalists will be baffled.
The media isn't interested in complex issues, and Bernie is the only candidate who understands the interconnected nature of many of the critical issues that should be discussed in this campaign.
Covering Bernie requires an understanding of the issues. It requires thought -- and work.
It's much easier to simply parrot the fear-mongering and scapegoating from the likes of Trump, Cruz, and Rubio.
