I think American leftists should stop treating voting as a means of achieving strategic political goals and assign it the seriousness it deserves - Something you can do if you have an hour free, but not something of any real priority.

It was the lowest form of political participation. Now that the "Choice" is literally between two different flavors of fascists who are actually engaged in actual genocide it's not something you should expend resources on that could be used elsewhere. If it you can work it in to your schedule, fine. But treating it as though it's important, at this stage in the game, is farcical. It's the sunk cost fallacy when the ship has already blown up, split in half, rolled over, and fallen to the bottom.
