Lease Issue: HOA fining me for political sign

Using a throwaway bc my boss knows my main. Quick background on my situation — any input appreciated.

HOA fining me for political sign. I've been dealing with this for about 2 weeks now and the situation isn't improving.

I have been renting for 3 years. My monthly rent is $3,827. We are on a month-to-month now.

What are my legal options here? Is it worth pursuing?

Just want to point out — the statute of limitations might be a factor here. In some states it's as short as 1-2 years. Don't sit on this too long.
