That's a ton of words that don't answer the question: why is Biden running again when he polls worse than "unnamed democrat"?

It also doesn't answer a whole lot of other questions that weren't asked.

Does he want to lose?

How should I know? Almost certainly not?

But I can't even begin to understand what you mean when you say actually it's good they sell weapons to Israel.

Do you think that if we refused then they wouldn't just go buy them elsewhere? It's notable that, for the first time, conditions have been imposed on how the weapons can be used. The conditions aren't as restrictive as they might be, but that's another signal that our "unconditional support" of Israel is in jeopardy.

We have always sold weapons to Israel. Stopping now wouldn't impact the war, but it would destroy any influence we do have over Israel's actions.
