I was just talking about Mayawati the other day...

And here she is on the BBC, in all of her glory. Mayawati isn't just a Dalit (an untouchable), she's a women who rose to political power completely on her own merits (no husband, father, brother, etc. handing her the political limelight), and she's set to completely upset the caste system. She might just be a spoiler, but she also could be the next prime minister.
