Obama sucks, Biden sucks, all establishment politicians including Trump don't give a fuck about you. He calls his supporters idiots, he has said he doesn't believe what he says to people but just says the things that his base wants to hear, like a TV entertainer, because that is his primary skill. He believes in nothing, and Kamala isn't really better.
It's possible to support people and actions that actually do help us all, there are many ways to help the country besides supporting sham politicians, who will do nothing to help us, will line the pockets of the wealthy and send more young people into endless wars.
Why do you think billionaires and CEOs love Trump? Because they know he will increase their profits, and he already has. This money comes from the lower class. The rich support the Dems too because they aren't much better if at all when it comes to corporate greed and theft of the people.
Supporting genocide seems like a pretty good redline to focus on though. When both candidates promise to maintain or increase the genocide, why does this sham of a democracy deserve to be supported? This electoral system and US imperialism doesn't have to be endless, partaking in the process only serves to legitimize the horrors commited daily.
