That tends to be a characteristic of ideology.     Because most people have at least something to base their opinion on, they make the mistake of thinking their presonal experience is 'right' and therefor everyone should eventually agree with them.  Political media pundints are grounded in past behaviors.   They totally missed the anger of voters in a system that seems increasinly corrupted.

Corporate media is a part of the corruption of the current political structure.  In Trump's words "It's HUGE".    Trump  knows image is more important that substance.  There's never been a canditate better at creating a sellable image.

Media is a tool, a very powerful tool.  It has no moral/ethical value.   It's wrong to say 'media' is liberal or conservative.   It's not the gu... err ...the media, it's the values of the person that choses to use it.
