A Civil War? No

 A rash of stories about the decline of our democracy and the possibility of a civil war.  See this in the New Yorker.

I'm not worried.  We've seen more risky circumstances in the past.  We forget the level of violence associated with labor unionization and the racism of the last century. We should be able to remember the divisions and violence of the late 60's and 70's, but we don't.

Our current polarization is different than in the past, but I don't think it's that likely to lead to wide-spread violence.  

If I'm to make a prediction, I'd say the level of racial/political motivated violence over the next 10 years won't rise above the level of past violence--i.e., homicides won't reach record levels.
