Are you joking? Or are you delusional? Have you linked the article you meant to? The article said that support of Israel doing genocide in Gaza is low. People obviously protested the military support for genocide, that much I believe is a given, as people did that in all major democratic countries even if those countries didn't support Israel in any way. And you're claiming that Harris lost elections not because she failed to convince her electorate that she will do something about it, but rather because this electorate protested? And you're blaming the fact that protests happened solely on the left, and think that broader populace was fine with genocide until leftists did something?
I'm pretty sure you have to be trolling at this point, but okay. Lets square it up. USA provided military and diplomatic aid to Israel, that allowed Israel to conduct a Palestinian genocide in Gaza. They could have stopped the support at that point, but they didn't. People protested spending their tax money on exploding children in Gaza, and USA government attempted to silence those protests, which included censuring Rashida Talib. Biden outright lied, claiming he saw photos of newborns beheaded by Hamas, a claim we know now was completely false. And lets not talk about the morality of it all, lets talk about optics, how that entire affair looked like to USA citizens. Democrats came out like blood hungry warmongers and Biden refused to do anything about that. He sometimes said that he asked Netanyahu to stop, but got ignored and rewarded Israel with more taxpayer paid weapons. That made Dems look additionally weak. Then the shift happened and Harris came into the forefront, where she every now and then said something to the effect of "she will do something to help", but continued to refuse to platform pro-palestinian voices and to promise to take care of Israel defences, for example here. She and her party has all the power, in the eyes of the people, to do something right now (or rather, back then, now Biden sent even more weapons), but she did nothing. One of her most clipped moments was her admission she wouldn't do anything differently from Biden, who already had all that blood on his hands in the eyes of the voters.
And you blame the protesters for asking her to do something instead of her for doing nothing/not enough? And not even the protesters, you're singling out the leftists as the people who caused harm here, while they asked the other side to stop, and other side happily enabled genocide. You do realise it's not just left wing and people interested in politics that care about people dying, right? Because aaaall of that above convinced people who didn't think about politics on a daily basis that Harris is unworthy of trust, which put her on a level playing field with Trump. Some of those people even bought the argument that Trump is anti-war and went to vote for him. And you think the left did it? That they were the sole force of disapproval that caused the protests to erupt, and not that protests were obviously justified and most likely reaction to bombs exploding children in Gaza?
The blame for that lies entirely on Dems, specifically on Biden and Harris. They could have done the popular thing and stopped sending weapons to Israel. They didn't, and it caused a lot of people to think worse of them because of that. Out of those folks, those who didn't want to understand politics and flet they didn't have anything to worry about regardless of who won, or had any other number of median voter thoughts, decided to stay home. Or vote Trump, since he confidently claimed he will stop that war, despite obviously not planning to.
Blaming protesters protesting an unpopular and sustained political decision of the ruling government for this government losing the elections is wild. The mental gymnastics you must need to perform to justify that take baffle me. The gall to blame the left specifically for all that, as if all people wouldn't respond to genocide negatively, is incredible. Overall, 10/10, would not reccomend. I don't intend to engage further in this discussion if that's the kind of bullshit you want to drag up, personally I find it sort of disgusting.
You're the one baselessly claiming that the left protested by not voting, the protests I spoke of were those where people came out in the streets, because those actually happened. Nothing in the article or my comments pointed to people on the left not wanting to vote. Also, you seem to have missed the part where regular people disliked the genocide.
