The Congress triumph over the BJP in Chhattisgarh and Rajasthan assembly elections has brought cheer to the opposition camp. The election in the three heartland states are seen as the final test of the BJP-led government's policies before Prime Minister Narendra Modi seeks a second term next year. The results are expected to boost the leadership quotient of Rahul Gandhi, who took charge of the Congress exactly a year ago. But the Congress defeat in Mizoram and a possible wafer-thin majority in Rajasthan are seen as causes for concern. All eyes are now on Madhya Pradesh, considered the biggest prize this time, where the party is locked in a tight race with the BJP. "We accept the people's mandate with humility". PM Modi said in a tweet.
