Waters has done NOTHING for her 'constituents'. She IS a master politician though, continually convincing the dumb and helpless that 'A vote for Maxine' will make their lives better. Those lives have never gotten better, and they wont be. She's convincing in her lies when she tells them that all of their lives are bad because of Whitie. Her race-baiting skills are amazing. 
PS. Her mansion is closer to $4,000,000, but you're right, it's not in her district. She's become too elitist (like all good liberals), to live with her voting masses...
