well wasting your vote if ur voting for congress. my calculation is simple congress has been in power since 47. only vajpayee govt a full tenure. so if u minus these years of vajpayee , vp singh, devegowda, gujral, charan singh etc it won't contitute more than 10 years. now a party who has been in power for more than 52 years has failed to bring its people above poverty line what have they done. now u can take example of japan which was devastated till the end of 2nd world war which is the same time india got its independence. the calculation is simple my friend...
