You’re not going to fix it by voting „harder”. It just makes you think you’ve done your part. But in all honesty the american democracy has been eroded for decades to the point where you have to choose between fascism and fascism later. You don’t reverse that trend by voting for kamala harris.
You also don't stop it from getting worse by not voting for Kamala Harris (barring better options). Fascism later is still clearly better than fascism now.
