Show me the better alternative to voting strategically. I never claimed the US system is great and perfect and directly produces wonderful results. Nobody over age 12 believes that bullshit, especially not lately.
In our deeply, deeply flawed system, consistently voting strategically is one of the most effective things we can do to effect change for good. Not perfect, but good. I urge all my fellow citizens to master the art of holding their noses and voting for the candidate more likely to improve their lives, or less likely to fuck them over. The alternative is accelerationism towards collapse, and the people on the left who say they want that are all woefully unprepared for the consequences. (The accelerationists on the right are also unprepared, but at least they have a lot of guns.)
As for doing more: I agree. AFTER we charitably elect the lesser evil, we should be calling their offices every day. We should be demonstrating. We should be engaging in civil disobedience. Our jobs do not end on election day, but we should never, ever allow the GOP to seize power electorally when it's so easy to keep them out. That is tying both hands behind our backs and making sure the people in power not only disregard us, but despise us.
