I think it is short sighted and kind of dehumanizing to assume they are drones who are merely waning to unite under one person. we can look at the reasons they chose to do this, the material realities that caused them to vote that way. You can only sway people if you understand why they do something so you can convence them to solve it in a better way
This feels like you are just assuming they want to be the “bad guys” It is more benifical to hear why they did what they did, and them we can talk and educate them out. Lots of this voting is based on fear, and we need to learn how to aswage there fear, or even meet there basic needs. What this ends up as is one side gave false promises they could solve this, the other said it was fine. Who would you chose if you could barily afford to put food on the table the one saying you will be fed or the one saying that there is no issue
