If you talk of qualification, What is advani's qualification, what was Vajpayee's qualification. What is Sonia Gandhi, Gauda's qualification?
You morons do not mind useless creatures like Vajpayee, Gauda, Narsimha rao ruling you, You love to be ruled by a foreigner, you do not mind criminals like Advani, Mulayam,Modi ruling you but you hate being a lower caste person being prime minister. All the curruption cases filed against her are fake, just to control her, malign her reputation but they have always failed because she has done nothing wrong.
And she will be the PM, no one can stop that ask any of your leader privately.
