The New York Times just compared media buy versus the free coverage Trump gets because of the media bias.    

He has only spent $10 million on advertising and his opponents and their PACS have spent mega-millions.  

Bush blew $82 million for nothing, Rubio is at $55 million for nothing. Cruz $22 million.  Trump has gotten $1.8 Billion (with a "B") for free while his opponents are in the $200 Million class each in the free category.  

They will never learn.
