Delhi: If exit polls are to be believed then Assam, Tamil Nadu and Kerala will see a change of government on May 19 and West Bengal will maintain status quo.
On the other hand, DMK may win in Tamil Nadu and incumbent Chief Minister J Jayalalithaa's AIADMK may be thrown out of power.
Only West Bengal is said to have bucked the trend and Trinamool Congress led by Chief Minister Mamata Banerjee is likely to be re-elected by defeating the Left-Congress alliance for a second consecutive term.
Counting of votes:
Counting of votes for the high stakes Assembly elections in five states will be held on Thursday morning with trends expected to be available by 11 AM. By 12 noon, a final picture could emerge on who would be the major players in the five states.
Election Commission officials said counting of votes, to commence at 8 AM, will be over by 3 PM.
The 'ballot unit' is switched on in the presence of senior poll officials and counting agents of candidates and the result command keyed in to get results per machine.
Where a paper trail audit or 'voter-verified paper audit trail' (VVPAT) has been used, the counting agent can call for a count of the paper slips in the drop box attached to the voting machine, but a final count is taken by the returning officer.
Once the results are declared, the names of the winning candidates will find mention in the gazette. The gazette notification will initiate the process to form the next legislative assemblies in the states.
What the exit polls said on May 16, 2016:
The BJP-led alliance could bag 79 to 93 seats in the 126-member Assam assembly, three exit polls said. A fourth survey gave the BJP and its two allies - Asom Gana Parishad (AGP) and Bodoland People's Front (BPF) - 57 seats, close to the critical half-way mark.
The India Today-Axis exit poll gave 79-93 seats to the BJP combine, 26-33 to the Congress and 6-10 to the All India United Democratic Front (AIUDF).
ABP-Nielsen predicted 81 seats to the BJP coalition, 33 to the Congress and 10 to the AIUDF.

NewsX-Today's Chanakya predicted a whopping 210 (plus or minus 14) seats for the Trinamool, 70 (plus or minus nine) for the Left-Congress and 14 rpt 14 (plus or minus five) seats for the BJP.
