Of course he is. The DNC spent the last four years with their heads up their asses thinking that this election is in the bag. They had time to set-up a different candidate, and they refused. They had time to strategize for a win, and decided to do fucking nothing.
I swear to god if Democrats throw this fucking election just like 2016 because they refuse to take fascism seriously, I will punch anyone who tries to claim it's the left's fault.
