This shows changing political charcter of BSP from "Tilak ,tarazoo aur talwar inko...." to "Brahmin Shankh bajayega...".This victory has brought through brahmin factor,establishing them as a vote bank again as once it was with congress prior to emergency and with BJP during Ram Mandir Andolan. Off course it is a wave of change in UP politics. One factor I feel also affected that people think Mayawati only can have a check on Gunda Raj in UP. no more hung--in UP.
