The Congress is confident about retaining the tribal vote, but it is believed to be on a shaky ground where the Muslims are concerned. In the last elections, the Muslims, who total six million of the 22-million population and are mainly concentrated in the Nagaon, Barpeta, Karimganj and Hailakandi districts, had voted en bloc for the Congress. It is difficult to say which way they will swing now. The AGP struck up a last-minute deal with the CPI(M), CPI and other like-minded parties and, given the Left's sympathy for the community in the past, the crucial Muslim vote may go to the new alliance.
