Ashok Gehlot government's big-ticket promise - cooking gas cylinders at Rs 500 - came into effect today, barely six months away from the assembly elections in Rajasthan. The move was well-received by the state's women, who are known to support the BJP, especially during the Lok Sabha elections. This is the biggest cooking gas subsidy being given in the country - crucial for the Congress in a state like Rajasthan that has a long tradition of voting out the incumbent for over three decades.
