2) fight election
3) awareness among voters regarding politicians

(meri raay mein central govt/state govt kabhi bhi aisee vyavastha nahin chahengey jismey bhrastachari ko saja ho. Jab politicians(all national and regional parties),corporate house,cbi, govt officials aur mafia ne desh ko kanooni tareekey se lootney key liye aapas mein haat mila liya hai aur agar koi unkey loot ke kaam mein badha dalta hai to ushpar cbi/ed/police/mafia se hamla kraney ki poori chhuth hai aisey mein kya koi tareeka kaam karega.---------------------------------------------aapki ray (your opinion)
