Liberal and conservative are essentially outdated political definitions. Right now it's the smug ruling class elite vs the rest of us. Not just here, in Europe too. Merkel is the so-called 'conservative' in Germany (we'll call her a typical Bush/Romney/McCain Republican) but probably the most hated 'establishment' pro-EU politician in that country. As a result, her so-called 'conservative' party is being outflanked by a new rising Eurosceptic political party. In Britain, it's Brexit. In America, it's Trumpism (for now). If Trump doesn't deliver "draining the swamp", others will come along and fill the vacuum. To Trump's credit, as Matthews points out, he recognized a political void ignored by both parties and rode that train straight into the White House.
I agree with you Joe- that's the need for the independent movement and the end of our two party system. That would be the real change needed.
