Many, many polls showed this very clearly. 77% of Democrat voters wanted an arms embargo, and over 30% of 2020 Biden voters in key battleground states said that this issue was serious enough to affect their vote.
> A Harris organizer who worked on youth turnout said that senior campaign officials gave them an order: When they sent out mass volunteer or fundraising emails and people replied by asking about Gaza, they were told to mark it as “no response.” The result? They seldom ended up engaging with voters on that issue.

So yeah, if there was one thing wrong with Harris, that would be it. That one issue would have changed the result, and as far as single issues go, I call genocide a pretty big one. It's kinda the biggest.
Far from the only issue though - campaigning with Dick Cheney was pretty fucking stupid, for one thing. Then there was promising to be harsher on immigration than Trump. Promising the world's "most lethal" military (we already are?) while trying to gaslight broke Americans into believing the economy was great. In general, trying to pick up right wing votes was a heinous 'strategy'.
Not sending arms to allies seems to be a good way to piss them off.
That's domestic and international law, by the way.
The question was, why did Harris lose, and the answer is that many Americans are still too decent to vote for someone who promises to arm the world's most live-streamed genocide.
Millions of potential Dem voters saw atrocities being committed with weapons sent by Biden and Harris. Every day, for over a year. Harris promised to keep doing that. That's viscerally disgusting, and a red line for decent people everywhere.
That's why she lost, which answers the question. Polls before during and after the election back that up unequivocally.
Now, you can argue that it's practical and more moral to vote for the lesser genocide all day, and you can point to all the ways that Trump is worse all night, but you can never, ever convince me that Democrats actually wanted to win more than they wanted to fuel genocide. Because they knew. They knew Harris' numbers, they knew the margins, and they knew what the polls were saying about Gaza. And then they campaigned with Dick Cheney. They managed to lose to a rapist insurrectionist, despite outspending him and his billionaires.
One more time - it's not the voters fault that they couldn't stomach voting for someone actively enabling the mass murder of tens of thousands of children, even if the alternative was openly worse. And it's weird that this is in any way confusing to people.
