Would you identify this politics with Hillary's "politics of identity"?
Identarianism has to do with dividing people into racial (in the European sense ie Polish or French or German etc.), nationalistic, sexist or other such groups and playing on feelings of exceptionalism or persecution in order to consolidate and hold power. This is, of course, the standard MO in democracies - pit one group against another.
I don't know anything about Ms. Clinton's "politics of identity". My guess, based on both the name given what I know about her, is yes its part of it.
