there are only two possible outcomes of this election
And there's the problem with all these responses in a nutshell. Shortsightedness.
Yes, there's only two possible outcomes to this election, and yes Kamala is the better candidate by miles. But your voting actions don't only affect this election, they affect all future elections. They're the background against which all political strategy is determined.
If you just bend over every time you're threatened with four years of some fuckwit in office, then you've committed to a political system where your opinion on policy ceases to be relevant. All that's required for a complete autocracy is for one party to be a unbearable fascist and then the other party doesn't even have to consider what the electorate actually think because they're the not-fascists, and that's all that's needed.
And this isn't even slippery-slope. It's happening right now. The not-fascists are actually complicit in war crimes and are still getting your vote . How much worse will it be in four year's time after they've had it proven to work? Why would they ever listen to the electorate on anything ever again?
