BJP president Amit Shah Thursday said the Feb 7polls to the Delhi assembly are a state election and not a referendum on the performance of the central government led by Prime Minister Narendra Modi."While this is indeed true that the good work of the government of India has its impact on elections, a state election cannot become a referendum (on its functioning) because of that one thing," Shah said in an interview to CNN-IBN channel."For us (BJP), every election is important and we take every election seriously. Development can only happen under the BJP," he added.Delhi goes to polls Feb 7 and counting of the votes cast would be held Feb 10.
