Here’s a test for measuring partisanship in American politics today: Turn on C-SPAN and – without looking at the name of the lawmaker on screen – see how long it takes to tell whether the member of Congress is a Republican or a Democrat. Chances are high that you’ll figure it out in less than a minute.  The extent to which American lawmakers’ speech reflects deep party divisions is unprecedented, Stanford researchers say.  Never before has American political speech been so partisan and polarizing, according to new research by Stanford economist Matthew Gentzkow.
