They might as well try to repeal gravity. Mad Maxine is going to play the race card and start screaming "deysa buncha white demon racists!",and get re-elected with a higher margin of the voters in her district than ever before.
She is in office for as long as she wants to be in office,and there is nothing you can do about it. Her typical supporter is even stupider than she is,so you are NEVER going to convince them they can do better.
