In defense of AAZ, I think he has become a pragmatic politician over time & I think he should be give a chance to run the country before we accuse him of crimes we think he maybe guilty of.
Also, let us not forget that AAZ spent what amounts to a life sentence in Pakistan in jail w/o ever being convicted of any crime, and govt spent 10s of millions of rupees hounding him all across the globe w/o much success.
Anyway, it comes down to this. You cannot deny/stop someone from holding a public office until he/she is found guilty of crime & as for as I know, AAZ was never convicted of any crime whatsoever. So, of he is elected & for sake of continuation of the constitutional system, let us respect that & treat him like constitutionally elected president, unlike his predecessor the tinpot.
Let us not forget that Swiss courts are still processing cases against him, president of a country is being prosecuted in another country. He is not "elected", just like Musharraf usurped Pakistan's power for 9 years Zardari usurped PPP's leadership after Benazir died and will now become "President" as a result of that. As "Some1" said, "Pakistan aasmaan se gira khajoor mai atka".
