Stevenson’s army, March 18

There are many causes of US political polarization. The two main parties have become more ideologically different; many people stay inside a partisan media bubble for their news; and there has been a “Big Sort,” with people increasingly living in like-minded communities. NYT dramatizes this with city maps showing what it calls “partisan segregation.”
Tom Edsall shows how partisan alignment is occurring with other issue and identity alignments.  [Read through the culture war commentary to get to the poli sci stuff. Like this.
And this.]
Russia has recalled its ambassador from Washington.
NYT has good summary of Biden’s emerging policy toward China.
NYT also explains why “free trade” is no longer politically popular.

DNI has new report on domestic extremism.
