evidence: One explanation for Biden’s progressive turn is that he has never been an ideologue. He has lodestars—standing up for the middle class, favoring unions, and so on. But those lodestars have led him to varied results. His superpower, it is often said, is possessing "this sense of where the Democratic Party is, where the median of the party is, at a given moment," as Khanna put it. [...] Something progressives admire about Biden is that he is a talented "reasonablizer" of their ideas. As Reich told me, "Biden is almost magical in his ability to make progressivism boring. He can say the same thing that Bernie Sanders has or AOC has and say it in a way that causes your eyes to glaze over." From progressives who are used to even their more modest proposals being tarred as communism, this is a genuine compliment.
