Politico: Clinton aides blame loss on everything but themselves.

The post-mortem you wanted (or feared), right here.

No matter who you blame, what the hell was she doing campaigning in Arizona (believing she could get it at the last minute) when the Rust Belt had slipped away? Seems she actually believed it was a victory lap. Her advisors, her internal polling systems were dead wrong. Her unsuccessful strategies seem to never have been judged or critiqued for performance.
