He's not wrong, but I don't think Obama's the right messenger here.
I vividly recall how he let the bankers skate when they destroyed the US Economy, how he let NYPD brutalize Occupy, how he allowed torture and his kill list, and his blood-soaked foreign policy. Heck, he even had the balls to walk into Flint and performatively sip a glass of water in front of people whose water had been poisoned for profit. Even Donald had it in him to pretend to be empathetic to Flint residents when he visited.
Five families, just on my street, lost their homes during his presidency. Multiply that times a few million and you get why Democrats didn't want to associate with him later in his presidency. (Not unlike how so many Republicans are distancing themselves from Donald right now.) Your performative empathy doesn't matter when you have real power to create meaningful change and you let bankers make people homeless for profit they don't even need.
Why this man is still so popular baffles me.
