Unarmed, for sure.
The party of JFK, Eugene McCarthy, RFK and Hubert Humphrey disappeared when people like Jimmy Carter, Joe Biden, Bill and HiIlary, Schumer, etc came along.
Obama promised change and failed miserably.
So we reload, get on the firing line and try again.
Purifying our party is essential, though.
Iraq is an unpardonable sin but there are many others. NAFTA, deregulation, three strikes, repealing Volker- the list goes on.

Vilifying Trump is fun, but if we can't nominate someone who denounces those mistakes and can produce meaningful change we don't deserve to be in power and Trump, or even someone worse will take control.
