Chief Minister Nitish Kumar Thursday said people in Bihar were voting for development and peace and that a final voter turnout of 45-50 percent would be encouraging.
"I am not worried about low voter turnout. Everyone has not got a voter identity card. It's summer season and everyone is not at their places," Nitish Kumar told reporters here.
"It's fair polling this time, there is no incidence of booth capturing or forced voting. And 45-50 percent polling in the state is very encouraging for us," he said.
"People have been voting for development and peace; it is a positive shift in Bihar," Nitish Kumar, who is also the Janata Dal-United (JD-U) chief, said after voting at his ancestral home Bakhtiyarpur near here.
Nitish Kumar left Patna by train in the morning for Bakhtiyarpur, 55 km from here where his mother and elder brother live.
Bakhtiyarpur falls under the Patna Saheb constituency, one of the three of Bihar's 40 constituencies going to the polls in the fourth phase of the elections.
The contest in Patna Saheb is between two showbiz stars -- Bharatiya Janata Party's Shatrughan Sinha and Congress' Shekhar Suman.
Voting began at 7 a.m. amid heavy security in view of the threat of Maoist violence.
About 4.89 million voters in the three constituencies of state are eligible to exercise their franchise to decide the fate of 57 candidates.
