If you mean a more favorable outcome in Palestine, I... don't think so. I mean I voted for Harris, and a mostly democratic ballot from top to bottom, but I really don't think she would have changed the behavior of Israel in Palestine or even significantly change U.S.A. actions that support that behavior.
But, she wouldn't have trashed our relationship with every trading partner, ruined the NIH and FDA, published military plans in the newspaper. She might have been better on trans rights, but maybe not. So, yeah a more favorable outcome overall, at least IMO.
That's just not true. There's a lot of change that is incremental and comes from within.
That said, if you have enough fighting the system to do that you absolutely can't find time to cast a vote, please do that.
And, I also agree that the system is going to be trying to change you instead, but it's going to be trying to do that whether you "comply" or participate or not. It is possible to vote without being instantly and irrecoverably corrupted.
