Against people that want to see the people of Palestine not be constantly bombed into oblivion. Trump’s US will be significantly worse for women and minorities, so most people in those groups will end up better off under Biden because at the very least the Democratic Party aren’t literally white supremacist fascists. Those that don’t vote for Biden will largely be doing so as a protest vote or through apathy, which is significant (especially when you can see the size of the uncommitted vote, which is quite significant, and I hope grows), but also self-defeating — so it makes sense for the Democrats to pander to the type of person that would vote for Nikki Haley (which unfortunately somehow has a demographic much bigger than the left) instead, since they wouldn’t necessarily be endangered as harshly by Trump and so need incentives to vote for Biden.
