She can't do anything until/if she assumes office as president.

Especially with Biden as president, literally nothing else matters. He literally went around congress to avoid like a week delay.

Now she could say she's going to be stricter on Israel, and it would probably gain some votes in the right states to have an effect.

But what would definitely happen is AIPAC would give just an unthinkable amount of money to trump.

That would 100% happen if they have the slightest doubts in the Dem party.

So like I've said:

She won't be great. But she's better than trump or Biden and we frankly have no option other than voting for her and hoping public opinion affects her position more than donor money immediately after an election.
