Not going to pay 50 bucks to read that article, but if the term "populist anger" is used there in its common meaning, it's not about "other side" at all. It's mainly about people feeling supposedly representative government has abandoned any pretense of representing the population and their interests, and that understandably makes some people feel bad about it. It's not about pissing off some imaginary opponent, it's about making the persons taking decisions hear what the population is concerned about. And yes, a lot of people supported Trump because they thought - and think (correctly or incorrectly) that Trump is more attentive to these concerns than the alternatives.
You're trying to say that policy and representation is the broad concern. The studies say otherwise. The whole of government is one part of the elite that conservative America wants to tear down.
Do you think "owning the liberals" is a completely made up thing? How do you think it compares to the phrase "owning the conservatives", a phrase nobody uses nor seemingly aspires to?
No, it's not the specific policy. It's the general feeling that there's no representation at all happening. And yes, people would certainly would want to tear down the elites that don't even bother to listen what their subjects want - it's exactly how it happened all over history, once the elites forget the population exists and has needs, the revolution is brewing in one form or another.
> Do you think "owning the liberals" is a completely made up thing
No, I don't think it's completely made up. I think it's by far not the main driver, and claiming like everything the right does, or even most significant driver for what the right does is this is nonsense.
> "owning the conservatives", a phrase nobody uses nor seemingly aspires to
A brief search (not using Google since their results are garbage now) provides ample proof otherwise. But my point is that spite in not a primary motivation neither for the right nor for the left. Since the right is by its nature more reactionary (I don't use it here as pejorative but as a description of action caused by another action), their actions can looks spiteful in more cases, but that's not the primary motivation, whatever the forum trolls say. For the trolls, on both sides, yes, this is a primary motivation, sure, and they obviously exist, but they are not the main or the only force by far.
