Voting for the second phase in the Assam assembly election was held at 39 constituencies today. 345 candidates including four ministers contested in the round. In 2016, the BJP did extremely well in these seats, winning 28 of them with its allies. This time, the alliance led by the Congress has given a tough challenge. The most crucial are 15 seats in Barak Valley, Assam's Bengali heartland, where people support the Citizenship (Amendment) Act. The BJP seems to have an edge here. But it's a polarised region with the number of Muslim and Hindu voters almost similar.
