I think it's more about being sick of an absolute lack of any attempt at representation. I will avoid the topic of race and come at this at a completely different angle because it was my experience.
I decided this would be the first election I would vote in, I have been apathetic for a long time. Cuss me or praise me it was how I exercised my right and I did it with thought. I decided to change that this year and I'll be damned if I'll vote uninformed, so I tuned into the first pres debate I've ever paid attention too.
I fully expected to see Trump lying/ talking out his ass and I had already seen some of the points of project 2025 so I already had an expectation. I hadn't really ever paid Biden attention and was curious, but honestly my vote was well decided. Again though I wanted to know exactly who I was voting for. I was shocked, I felt deceived, but above all I thought " this is the elected official that is supposed to represent my ideals?". Which he already wasn't and I had made so many many small concessions, it was just the straw that broke the camels back. I felt all the anger and frustration that I had quelled resurface with vengeance. Now I recognized even in the moment this was an emotional knee jerk reaction, so I decided to watch every interview after to find genuine motivation to vote for Biden. Never did, it was just Grandpa refusing to even acknowledge giving his license up after ramming into a pharmacy with his car. Biden always spoke of the past when asked about inflation, everyday struggles, his accomplishments, his wealth, his political career, half the shit he referenced happened before the birth of my parents. The entire time I just felt so disconnected from him as a representative of my vote.
Now I'm not trying to justify not voting because of this, you should always vote and I'm trying to be better as well. I'm just saying I can empathize with how hard it is to be motivated to vote when you already don't feel represented whether that's ideologically, physically, racially, gender, region, or whatever it's all going to play into it, consciously or unconsciously. Even when you vote, you still can feel powerless. I suppose I can't say that for sure yet but I am pretty positive I will about that because the broken things I want to see fixed wouldn't start to mend immediately after voting because of how broken they are and how complex the solution probably will be, but I'm trying to have hope long term.
