Hypothetical question

I'm dealing with a situation and need some guidance.

HOA fining me for political sign. I've been dealing with this for about 13 months now and the situation isn't improving.

I have been renting for 2 years. My monthly rent is $2,621. I have a written lease.

Has anyone been through something similar? What worked for you?
