Well, I'd support even kala choor (maybe zardari is kala choor???) than support any military dictator no matter how good he is. Having said that, why are we depending on individuals? And, if Zardari is elected legally & constitutionally who are we to argue against it?
No doubt that an elected Zardari deserves to be President (and Pakistan deserves that too). Nevertheless, regardless of Zardari gets elected or not, a person only support those who is similar to them in values, unless they are ignorant and following a person (or system promoting the elected person) like Zombies.
As for Mushrraf, I don't care how good he was (I think he gets credit for lots of things which he had nothing to do with). He was illegitimate self-appointed dictator, who was doing all he could to hang on to kursi. In 8 years he destroyed every institution in the country, and then at the end he gifted us NRO, Zardari and Shareifs.
Musharraf was as much legitimate or illegitimate in power as anyone could be (actually, there is no such thing as a person illegal or illegitimate in power, but these are words of losers and every loser throughout history have used it).
Musharraf done something for his own kursi: ... I do not see any truth in it other than lies and propaganda. I could not see that Musharraf gained from NRO or there was anything he could have gained when NRO was issued. Rather it was known from day one that he would lose because of NRO. When Musharraf issued NRO he was in power and anyone in power love to keep cases of people in opposition open so that he/she can victimise, torment and pressurise opposition using those cases. Musharraf did not started any of those cases and it was something he inherited from past, started by those in power to victimise, torment and pressurise oppositions. Many of those cases may be true too, still undecided, so that it can be used by people in power for victimisation, tormenting and pressurising. Many cases were lingering on because guilty party had enough support in judiciary to keep it lingering.
Only a brainless would believe that a person in power could gain something by closing cases of opponents and giving them pardon. As for Nawaz and Zardari (or any crooks in Assembly), it is propaganda and lies that they are gift of Musharraf, as they are not gift of Musharraf but those who supported, voted, and elected them (due to their own personal interest or being brainless Zombies).
