The people's opinions of Trump are based on the Mainstream Media's interpretation of facts. Everything is down to good guy/bad guy based on a few public pronouncements. Nothing in depth really about what they are really about. Also, nothng in the Canadian media as to why so-called fringe candidate seem to be getting a lot of support.
The US mainstream media is corporate owned, and you get the corporate message. Corporations now have more sway with the US government than ordinary electors. Many people now know that they are being screwed by corporatism, including being screwed by the big banks that are too big to fail. The standard of living in the US has been falling now for at least the last 30 years. People are waking up to that fact, and what you are seeing now is a revolt against mainstream politics. In 1933, FDR warned the US oligarchs that he would destroy them if they didn't share the wealth with the US people. They did after that. Wiht Obama, impossible as the corporations and banks behind the scenes own him.
The US is still, however, a democracy. That democracy is manipulated by the MSM in order to get the correct leader, already chosen by the corporatists who run the US government. So they bring things down to the very simple level that most people can understand: white hat/black hat. Only now, mainstream media is losing its viewrship in great numbers as people turn to internet media, as its' apparent to many that MSM is just propaganda for the richest 1%.
Sanders and Trump are a reflection of that revolt. Trump, as a brilliant salesman, and knows what to say to strir the masses. Hillary fumbles about , trying to explain the $600,000 she got from Goldman Sachs. Hillary has less and less credibility, and the fact that she got a boost from the superdelegates has a lot of people turned off the Democratic Party. It is telling that a lot of US republicains are swithing to Hillary are neocons, like Robert Kagan. Thats because Hillary is a neocon in her own right and Trump isn't. Hillary's foreign policy record is dismal: Libya, Syria, Iraq, Afghanistan etc etc. Nothing but a series of failures. Expect more of this if she wins, and expect a confrontation with Russia and possibly China.
