I don’t love how it played out either but it was the delegates we voted for that elected kamala as our nominee. It was our representative democracy at play in a less than ideal situation when biden dropped out at an awkward time. And kind of the point of a vice president.
Its this or the guy that said he’d be dictator on day one and that no one would ever have to vote again if he is elected. You decide what you want to vote for.
I originally wanted to do what you’ve done, but eventually fell on the idea that the country is essentially beyond saving. Should this hold true, the best option then is to join a grassroots movement and begin building an alternative economy from the ground up as a ready replacement for the collapse of the current system. Join a socialist organization, work for a land trust, start building cooperatives and alternative food systems, etc.
