Thanks, the paper looks interesting!

Though I wouldn't call it "very far". Solidarity peak is the same as it was around 2008 (the Great Financial Crises I guess), regulation and waste views are interestingly conflicting, the anti-corporatism shift is happening across all cohorts, so again it doesn't seem like the Dems are going that much more left.

The views of immigration are very polarized. That's interesting, and probably the result of the excessive media coverage plus the very real recent underlying events.

The emptying out of the center is the effect of Trump.

Though it'll be interesting what will happen in the upcoming 2020 primaries. And we'll get a lot of data about what people value. (With the usual caveat about polling and statistics.)

Here's more from the Economist, check the chart: https://www.economist.com/united-states/2018/09/20/far-left-...

This is absolutely bonkers wrong. The US has shifted dramatically rightwards since 2014, and the right has shifted even more dramatically so.

Do you have research you can cite?

Well I can point to the literal white supremacists who are literally marching in the street with torches and chanting "blood and thunder" which is a distinctly post-2016 phenomenon.
