Over a quarter of Maharashtra's 8.35 crore voters exercised their franchise by Wednesday afternoon in assembly elections that has pitted the BJP against virtually everyone else.
The voting percentage until 1 p.m. in certain constituencies was as low as 20 percent but exceeded 45 percent in some.
Along with balloting for the 288-seat Maharashtra assembly, voting also took place for the Lok Sabha by-election in Beed. The seat fell vacant following the death of union minister Gopinath Munde in June.
The main contenders for power are the Bharatiya Janata Party (BJP), whose campaign was spearheaded by Prime Minister Narendra Modi, its estranged ally Shiv Sena, the Congress, the Nationalist Congress Party (NCP) as well as the Maharashtra Navnirman Sena (MNS).
The battle has become a matter of prestige particularly for the Shiv Sena, which has gone on a verbal offensive against the BJP for breaking a quarter-century-long Sena-BJP alliance ahead of the election.
Other parties have also attacked the BJP more than any other party.

In other big advertisements released in the Mumbai media, it virtually termed the rival parties as demon king Ravana.
"Ravana was not killed by a 'hand' (Congress symbol), a 'clock' (NCP) or a 'flower' (BJP's lotus). He was taken down by a bow and arrow," the advertisements said.
