Why on earth would people have voted for Donald trump?

I know Kamala Harris was seen as extreme on some sociopolitical positions but Donald trump is another extreme. Why vote at all if the choices for candidates were not great? I mean I didn’t vote because I don’t think most politicians care about the average person and I don’t think my vote counts anyway. The powers that be will put whoever they want in power I’m sure but my god Donald trump and his cabinet are an embarrassment for what America was supposed to stand for. Even my sister voted for Donald trump because she said he was lesser of two evils and Kamala Harris was too left wing for her. I’m disappointed that she would vote for trump buti I still love her to pieces. My sister is the daughter of immigrants but voted for a cabinet that doesn’t readily embrace immigrants. And for the record yes my family came to the United States legally decades ago. She is also sick of the transgender push and is pro life and thinks abortion should be canned with the exception of rape, sexual abuse/incest, and maternal death. She is becoming more conservative as she gets older. She thinks undocumented immigration needs to be gotten a handle on it but she doesn’t agree with how ICE and the trump administration are handing it. She doesn’t want her hard earned money to be taxed even more for someone to cut their dick off ( her words) . She voted for someone whose cabinet is repealing protections for people like me lgbtqia + and she thinks transgenderism is a mental illness. She calls the far left wing “ libtard”. I’m opposite to her in that I am moderately liberal whereas she’s moderately conservative. Well I didn’t see this coming. What can you do?
