Rajasthan, one of the three key cowbelt states going to polls in the last round of assembly polls before next year's national elections, is one where the Congress is hoping to win big. Over the last five elections, the state has exhibited a "revolving-door policy", never voting in the incumbent government. The Congress is hoping to ride this tide. But pointing out that the state had kept the Congress in power for 50 years, Chief Minister Vasundhara Raje claims her government has worked tirelessly and she is "happy about the general... sort of mood".

The state has 21 bellwether seats to watch out for during the counting. Kumbhalgarh has always voted for the party that had won the state in the last 37 years. Sujangarh has done the same for 24 years.
