"Do populists on the left and right have enough in common that they could join together and challenge the status quo establishment?"
I'm not talking about political party "bi-partisianship" in Washington. I'm referring to activists who advance positive change on the basis of promoting principled values and not necessarily through party politics.
The notion of "principled" seems to be a core concept that helps define what I'm talking about above. When I say "principled" I mean that they have consistent political views. Their ideology is consistent. Because, when somebody espouses what is supposed to be a core value, like saying that "freedom means minimal government intrusion in our lives," but then turns around and supports capital punishment at the hands of the same bumbling, corrupt, excessive government they want to limit.... I see it as inconsistent at best and perhaps even hypocritical.... they certainly aren't principled in their political views, because they are flip-flopping on their principles.
Since I come at this subject from the Left, my perspective is to ask the question,
"Which people on the right could be partners with people on the left?"
and up crops the answer,
"principled people who share common concerns about abuse of power in our country. People who are concerned that our democratic ideals are being subverted."
