Weird that this has to be explained this late into the game but…
Trump is running on the promise of enacting fascism and using state power to mete out retribution to the ‘undesirables’ that his voters blame for their lack of power. To this end there is nothing he can say or do that will make them not vote for him. He is promising power and as long as he wins his promise is kept.
Kamala is running on a platform of ‘not fascism’ and to that end she does need to provide a coherent alternate worldview to mindless retribution. It’s not enough for her to walk the middle of the road and say as little as possible. She needs to give people a diametrically opposed worldview. She needs to be capable of explaining why fascist retribution isn’t good or helpful. She can not just be a diet Republican. She needs to have coherent answers to their obvious bullshit.
Hope this helps. Horrifying that the people who are a decade into Trumpism and ostensibly responsible for stopping it don’t seem to have the slightest clue what motivates it or how to counter it.
Because fascists can always move father right. You can’t out Republican the Republicans.
