The rise of White identity politics

Conservatives complain about ‘identity politics.’ But the most politically influential form of identity politics is arguably white identity politics. In the latest “Reality Check with John Avlon: Extremist Beat,” Avlon traces its origins from the blatant racism of the KKK to the more subliminal form of anxiety in Birtherism and nativist anti-immigrant politics. CNN's Sara Sidner and Elle Reeve join Avlon to discuss how this anxiety is expressed today in this first of a two-part look at White identity politics.
