AS hectic bargaining continued, the big question on Saturday was: will Mulayam Singh Yadav ultimately back Congress? The Samajvadi Party chieftain might offer support on a variety of issues, but hes his own man when it comes to UP. Not so long ago, Mulayam could be heard repeatedly berating the Congress for not showing enough enthusiasm in the cause of bringing down the "communal and fascist" BJP government . But when the Congress finally made its move, the powerful Yadav chieftain had other reasons to be disturbedSalman Khursheed was making a mark in UP and there was talk of the Muslim vote going the Congress way. In 1989, the Muslim vote bank post-Babri Masjid and Shah Bano had moved away from Congress. In the decade since, Mulayam has assidously cultivated the minorities.
