When will the pressure be applied? It sure as shit won’t be the current election, so you’re betting on it still being a thing in 4 years that they can change their mind on?
Calling your representatives changes more opinions than “not voting” or “voting for someone else” in a two party system.
And if you’re in this position where you see this all as fact, then what is the alternative?
IMO there is none.
Trying to rebuild the system at the time of an election is the wrong time. You have two options - because that is the reality you live in (right now).
Work on building something better AFTER the election, change the system, fix it for the future. But for NOW, you get a choice. Not voting (in this system) is a vote for ambivalence, and you dont seem like the person that doesn’t care.
But importantly, work to change the system later. You have valid concerns and the system you are in is broken, but you can make a change.
Edit: to not be misconstrued, I agree with the issues at hand that you’re highlighting. I’m just saying that the alternative is worse and that is a likelihood in this reality no?
