Impossible to directly endorse, but then explains she’s the only option to stop trump…

From the second and third paragraphs of your link:

But the Uncommitted National Movement, which arose out of organizing efforts to get people to vote “uncommitted” in Democratic primaries earlier this year in protest of President Joe Biden’s handling of the Israel-Gaza war, also said in its lengthy statement that it opposes Donald Trump. It said the former president’s “agenda includes plans to accelerate the killing in Gaza while intensifying the suppression of anti-war organizing.” And it urged against votes for any third-party candidates in November, which leaders say would help a Trump victory in key swing states.

“We urge Uncommitted voters to register anti-Trump votes and vote up and down the ballot. Our focus remains on building a broad anti-war coalition both inside and outside the Democratic Party,” the group said in a statement.

They flat out say what matters is stopping Trump and that third party votes are a waste…

Who do you think that leaves?

I feel like my summary was accurate:

This is the best we can get, it sucks but this is who we should vote for
