Mayawati is no Dalit. She is opportunist political figure. So far, she has played her cards well. But there is a saying that one can fool some for some time, but not ALL all the time.
You and others will see her down fall as quickly as her rise (through opportunistic alliances). I am sure by now SP and BJP and the INC have learnt their lessons on whose shoulders she stood to gain this position of UP CM.
