Even CNN-IBN, which is heavily biased against BJP and has been vigorously promoting Mayawati, has shown in its poll that Mayawati will make little inroads into upper caste...just putting up a 100 Brahmins will not do...you also have to treat these groups with dignity and respect, which she has never ever done. She made all types of efforts to woo Muslims, but still has no established trust in that community. SP has Yadavs, Muslims and good section of Upper Castes supporting it. BJP has most of Upper Castes and other OBC's...Mayawati still remains mostly confined to Dalits.
