People in NA, Senate and provincial assembly are representatives of the people and what they vote is what people want. Presidential election should clear what people really want in Pakistan. People want Zardari to be President of Pakistan (well, something achieved because Thug Nawaz wanted Zardari badly as President, so he did all to make President Musharraf .
I see, is that why he fielded his own candidate for presidency? Also, you are forgetting which thug FIRST nominated Zardari for presidency and whose party filed his papers! Aap ko kaafi pasand hai woh party :)
