My mother keeps asking why can't they do anything to stop Trump?

We talked for about an hour tonight and I told her that I don’t know what they can do? She will be 83 years old this December and she is scared that he will stop pension from the Post Office also take my late father social security away too! She is doing okay for the most part and I help her out by paying her rent since I stay there when I take time off from work also I pay a few other bills for her. I wish I had the answers for her, but we both agree to pray that Biden will win! With me being on the road and her living by her, she afraid of will happen if Biden doesn’t win, but so am I! I am afraid for the whole country too! Trump has played his base into believing his con man act is the best way to save our country, but they are blinded by his greed! This includes many of sisters and brothers! Lord helps all!
