Haryana Chief Minister Manohar Lal Khattar said he wanted to send across a message on polling day as the state votes today to elect its next government. "On every important day, it's important to send across a message. Today, environment is an important issue," he said as he cycled to a polling booth in Karnal to cast his vote. Earlier, he took a train to reach Karnal. "I wanted to travel like a common man," he said. Voting began in 90 assembly constituencies in Haryana this morning.
