The atmosphere is so heated, and the statements are getting more and more extreme. Let’s just assume Harris wins the election. After a campaign like this, how could you ever have a normal relationship with your pro-Trump neighbor/father-in-law/Uncle/Barber or what ever again?
You have to think of the lack of primary as a sunk cost. The decision in front of you is independent of all previous decisions.
So, we just going to reward that?
Certainly not. But choosing to punish at this precise opportunity would be like shooting your own feet.
Punish at the local level. Punish by supporting voting reform. Etc.
Boycotting is a powerful tool and should be respected as much as voting
Not voting at all is just laziness.
Spoiled ballots may have some long term influence. But they have no power over the election being boycotted.
