... as though the other realistic alternative would be better for your stated anti-genocide cause. (Pro tip: It'll be worse.)

I've said elsewhere, we have FPTP and the electoral college. This makes for a two party system, with the scales tipped in favor of the right.

This is a binary choice. Either Harris will win, or Trump will win. Failing to vote for the one you hate least is essentially the same as putting the one you hate most into office.

This isn't fair, it's fact. It shouldn't be this way, but it is. If you want it to be different, then we need ranked choice voting, and a few more states need to get on the NPVIC. If you want it to be different, which administration do you think will allow you to campaign for those changes? If you want to end genocide, which administration do you have any chance of doing that with?

You may not remember, but politics in the US hasn't been this weird in my lifetime, and I'm old. But you know what? You're in California, Louisiana, Illinois, Utah? -- you vote however you want. Ain't gonna make a difference; those states and plenty of others are on lock. PA, MI, WI, NC, GA, AZ, NV: voters in those states are going to make the difference this time.

Oh yeah, did you also know that the arms deals from the US to Israel are an ongoing thing, for a long, long time, passed by Congress? And that the president has limited ability to do anything about them? And that Biden wanted to pause at least one of those shipments? And that House Republicans didn't let him? (I'll find a source on this in a bit.)

That whole thing isn't something that a president can just wave a magic wand and change on a whim, I mean, unless the president is a fascist, but that's a hell of a dice roll.
