That group already endorsed her weeks ago
You mean with the statement...
Vice President Harris’s unwillingness to shift on unconditional weapons policy or to even make a clear campaign statement in support of upholding existing U.S. and international human rights law has made it impossible for us to endorse her https://www.politico.com/news/2024/09/19/uncommitted-no-endorsement-harris-third-party-trump-00180002
Is that the one in which they endorsed her, the one ending "impossible for us to endorse her"?
Yes. That's right. And it's entirely Harris's fault. No one else's. She could change policy and earn their vote. She doesn't, and so hands the election to Trump.
Yet you're such a sycophant that instead of outrage at her, you're outraged at the voters whom you think somehow owe her a vote. You're outraged at the people practising democracy for not falling into line with the authoritarians trying to undermine it.
Harris will win more votes than she will lose if she changes policy on arms sales to Israel. That is what the evidence shows - overwhelming support for such a policy among previously Democrat voters and abstainers in key states.
Candidates changing policy to meet voter's expectations is exactly how democracy functions, even flawed ones like the US normally vaguely track voter preferences.
So if Harris changed policy she would not worsen her support, nor would she be doing anything other than her job.
The fact that she isn't will be the single fact responsible for a Trump win, if he wins. Nothing else. Every other person involved would have been acting accordingly, only the Harris team are out of line.
They are acting undemocratically, and probably illegally, backing a genocide. And you're defending them, and attacking the people supporting democracy and peace...
