That's the same machine that had been running against the Clintons for decades by the time Hillary ran for 2016. I doubt they had to spend a dime on convincing their base not to vote for her because they were already primed to see her as the devil incarnate. They just had to sway a few independents and they were good to go.
It's why I'm genuinely concerned that AOC might never get a fair shot at the presidency. Maybe if the GOP falls apart post-Trump like some are speculating she could win out against a fractured opposition, but I still worry about that visceral reaction from years of conservative media demonizing her.
