You need to vote for the next several years, no matter what, because you still have a chance.
Once corruption becomes the default, then you are REALLY screwed. Because it kills hope and the faith in the future in the most corrosive way possible.
The death of morale is a far worse and insidious fate that will make today look like a high point.
Of course I’ll vote, and be more active in protests and campaigns, but TBH the general vibe is that it’s already too late. It’s that bad.
