How though? And more importantly, why? Like, what “leeway” does Kamala have to say anything different than she already has, which she could shift to?

Maybe after she wins yes, but at this point the choices are Trump vs. not-Trump, so I don’t see how a vote for a third-party would help in this case. At one point, with Bernie Sanders vs. Hillary Clinton there were different thoughts about how a vote for Bernie would cause Hillary to shift more towards the left - but most of that again gets back to the nomination process, not the final show-down between the two parties, and after that was a disastrous example of how voting for the 3rd-party candidate didn’t help the democratic party shift, except in the sense that it handed literally hundreds and hundreds of judicial nominees to the Republican party that, among other things, ended the protections of Roe v. Wade.

Two months ago the situation with Biden was VERY DIFFERENT than the situation now faced, with Kamala. Back then we could - and yay, did! - shift and pivot to adjust to the harsh realities that he was not capable of running again. We very likely would have lost if he had. But that was then, and this is now.

Anyway I think that I’m preaching to the converted here, so maybe I just misunderstood something that you said. Tbh, I don’t agree with your take on the OP - I think it really does show voting not for a 3rd party but voting for the other side b/c “bOtH sIdEs ArE tHe SaMe” (the title of the post), specifically wrt genocide. I think that b/c there are only 2 tracks shown… Also, the genocide being mentioned implicitly in the graphic (“but worse…”) shows how its focus is on short-term effects immediately after the election, not long-term ones about telling the Democratic party how the American populace would very much enjoy it if it would become more liberal if they would please and thank you very much.
